I'm trying to setup ruby on rails environment on termux on android. I want to use 2.1.10 ruby. All I found was apt install ruby-dev or pkg install ruby-dev which installs the latest version of ruby. any suggestions?
You can install rvm.
0. Recomendation: install tmux and zsh, and change zsh as default shell. Oh my Zsh worked. Powerline fonts too (by install termux-style script)
Let's install rvm:
1. Install gawk, curl and tar packages:
apt install curl gawk tar
2. Go to rvm.io site and just copy 'Install RVM' command, look' like:
curl -sSL https://get.rvm.io | bash -s stable
3. Add this line [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" to your ~/.bashrc or ~/.zshrc file
4. Now your shell must writing a syntax PS problem, just open rvm script and edit it:
vi ~/.rvm/scripts/rvm
Now you must found a block like:
case "`uname` in
(CYGWIN*|MINGW*)
... etc ...
Just replace the 3 initialization variable __shell_name strings with this:
__shell_name="gawk 'BEGIN{RS=\"\"}; NR==1{print; exit
}' /proc/$$/cmdline | tr - '\0'" ;;
Restart shell
Now you can install ruby from rvm. Usage at rvm.io
P.s.: jruby not supported while you don't found solution for install jdk and jre from Termux).
P.s.: sorry for bad English.
apt install ruby-dev installs ruby 2.5.1-1
And that's the latest version, I think.

I just walk-through with the installation of Ruby on Rails on Ubuntu using RVM.
First I have logged in as the root user.
Then I started with the following commands.
\curl -sSL https://get.rvm.io | bash -s stable --rails
It has been installed without any error.
source ~/.rvm/scripts/rvm
When I run this command. It showing the error as bash: /home/XXX/.rvm/scripts/rvm: No such file or directory
I added the [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" command in my .bashr file.
Install RVM:
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
Now you will get a success message. Then, run this command:
\curl -sSL https://get.rvm.io | bash -s stable
See http://rvm.io/ for more info.
I think they may have moved some files around fixed with:
source /usr/share/rvm/scripts/rvm
After installing rvm, try:
source ~/.rvm/scripts/rvm
If the above command throws some issue, try this command:
source /usr/local/rvm/scripts/rvm
Firstly no need to go for sudo access while installing rvm, just follow the very basic commands below
$\curl -sSL https://get.rvm.io | bash -s stable
This will install rvm.
$ rvm list known
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-p374]
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p320]
[ruby-]1.9.3[-p545]
[ruby-]2.0.0-p353
Install a version of ruby as required.
$ rvm install 2.0.0-p353
Now you can use the version of ruby for which you need to install rails as a gem.
$ rvm use 2.0.0
Also you can make it default if you want so
$ rvm use 2.0 --default
Next you can install rails as a gem.
$ gem install rails
gems should never be installed with sudo access as they change from project to project. rvm helps in managing the different versions of ruby in one m/c. You can also use gemsets to isolate gems and specific versions from one application to another.
just create ~/.rvm/scripts/rvm directories, then try to install rvm but make sure you are not logged in as root.
This source /usr/share/rvm/scripts/rvm works for me on ubuntu 20.04.
I changed the local in /usr/local/rvm/scripts/rvm to share
I assume that you have installed the rvm.
Is generally not recommend to install RVM as a root user because of umask security risk. Try running these commands as a user.
Downloading RVM (Do not sudo this command)
\curl -sSL https://get.rvm.io | bash -s stable --rails
Then you'll need to add the location to sources(You'll probably need to reload your bash for rvm to work)
source ~/.rvm/scripts/rvm
You can install your desired version like so(replace ruby_version with one you would like to install, eg 2.1.4)
rvm install ruby_version
To list the available version on your machine
rvm list
To use a version of ruby run
rvm use ruby_version
If you have any trouble refere to the RVM website
As root, you traditionally don't have a /home folder. Root's home is different than a normal user.
You very likely don't want to install RVM as root.
Please do read the information at http://rvm.io specifically the installation notes.
Can you use sudo find to locate the correct path of the rvm directory? If you find the path, you should be able to rerun the source ~/.rvm/scripts/rvm command with the correct path.
Also, I fully agree with the previous answers about not creating it as root. DigitalOcean was a pretty good tutorial on adding users https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-14-04
Alright so when you get a failure message "No such file or directory",
type
\curl -L https://get.rvm.io | bash -s stable
in your terminal.
There will be a GPG signature verification failure.
Bellow that failure there would be a link for github and a key something like this
gpg2 --recv-keys 409B6B...
So download a tar file from the github link and run this code to install GPG:
sudo apt install gnupg2
and run that key :
gpg2 --recv-keys 409B6B...
next run the code:
\curl -L https://get.rvm.io | bash -s stable
it will show you installing the rvm
and then you can run:
source ~/.rvm/scripts/rvm
thats it you are good to go
If you install rvm via apt-get you can add the following line into ~/.zshrc or ~/.bashrc
source /etc/profile.d/rvm.sh
For me all the above methods didn't workout.
After the installation and updates, still the terminal shows this "error bash: /root/.rvm/scripts/rvm: No such file or directory"
The simple method which helps me to solve this error is :
Show Hidden Files
Go to the Home (where the bash scripts are stored)
Edit the .bashrc
At the bottom you can find some lines about rvm
just clear the rvm lines and save the file.
Open terminal and check it.
Your surest bet is to use home brew. Funny part is if you try brew upgrade ruby, you will have an error if brew wasn't used to install ruby in the first instance so use:
$ brew install ruby
Then afterwards use
$ brew upgrade ruby
You may need to close and reopen your terminal to see the effect of the upgrade by typing
$ ruby -v
I am trying to install Ruby on Rails using rvm on ubuntu 12.04. I am following the steps given in https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm , but I am unable to install Rails successfully. When I run gem install rails, it does nothing.
Previously, by using the above link, I have successfully installed it several times. But this time, i couldn't.
Output of
gem install rails -V:
HEAD https //rubygems.org/specs.4.8.gz 302 Moved Temporarily
HEAD https //s3.amazonaws.com/production.s3.rubygems.org/specs.4.8.gz
200 OK
GET https //rubygems.org/specs.4.8.gz
302 Moved Temporarily ...
GET https //rubygems.org/quick/Marshal.4.8/rack-1.4.5.gemspec.rz
302 Moved Temporarily
It always stops at this point. Need some guidance to successfully install it.
Step One — Install Ruby with RVM
Before we do anything else, we should run a quick update to make sure that all of the packages we download to our VPS are up to date:
sudo apt-get update
Once that's done, we can start installin
g RVM, Ruby Version Manager. This is a great program that lets you use several versions of Ruby on one server; however, in this case, we will just use it to install the latest version of Ruby on the droplet.
If you do not have curl on your system, you can start by installing it:
sudo apt-get install curl
To install RVM, open terminal and type in this command:
\curl -L https://get.rvm.io | bash -s stable
After it is done installing, load RVM. You may first need to exit out of your shell session and start up a new one.
source ~/.rvm/scripts/rvm
In order to work, RVM has some of its own dependancies that need to be installed. To automatically install them:
rvm requirements
You may need to enter your root password to allow the installation of these dependencies.
On occasion the zlib package may be reported as missing. The RVM page describes the issue and the solution in greater detail here.
Step Two — Install Ruby
Once you are using RVM, installing Ruby is easy.
rvm install ruby
The latest ruby is now installed. However, since we accessed it through a program that has a variety of Ruby versions, we need to tell the system to use the version we just installed by default.
rvm use ruby --default
Step Three — Install RubyGems
The next step makes sure that we have all the required components of Ruby on Rails. We can continue to use RVM to install gems; type this line into terminal.
rvm rubygems current
Step Four — Install Rails
Once everything is set up, it is time to install Rails. To start, open terminal and type in:
gem install rails
This process may take a while, be patient with it. Once it finishes you will have Ruby on Rails installed on your droplet.
i did this:
sudo apt-get install git
sudo apt-get install curl
curl -L https://get.rvm.io | bash -s stable --ruby
sudo apt-get install git-core
source ~/.rvm/scripts/rvm
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
rvm autolibs enable
rvm reload
rvm requirements
sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
rvm install ruby-2.0
curl -L https://get.rvm.io | bash -s stable --rails
Hope, it helps.
Refer Installing rvm wih stable ruby, use this command
\curl -L https://get.rvm.io | bash -s stable --ruby
After successful installation of ruby, install rails as a gem.
gem install rails
The most basic Vagrant box you can find to get Rails on Ubuntu. (This uses Ubuntu 14, but you can just change the box, should work roughly the same).
https://github.com/joelgerard/rails-vagrant
Also, checkout the bootstrap.sh if you want straight forward BASH.
I am trying to install RVM on my Ubuntu machine.
I have used curl to get RVM, but some RVM commands (install, requirements) throw this apt-get error:
There has been error while updating 'apt-get', please give it some time and try again later.
For 404 errors check your sources configured in:
/etc/apt/sources.list
/etc/apt/sources.list.d/*.list
type rvm | head -1 returns
rvm is a function
-bash: type: write error: Broken pipe
which gem
/usr/bin/gem
I have checked the "Run command as a login shell" option
Steps followed from this tutorial:
sudo apt-get install curl
curl -L get.rvm.io | bash -s stable --auto
. ~/.bash_profile
rvm requirements - doesn't work properly
I have also looked at the official RVM documentation, but it seems to be very similar.
Any ideas?
UPDATE: I managed to do it. I disabled all the third party ppa URLs and it installed smoothly.
There are some important packages your system needs before install rvm. Run at the terminal:
sudo apt-get install build-essential openssl libreadline6 libreadline6-dev \
curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev \
sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake \
libtool bison subversion nodejs
Then install rvm with:
curl -L https://get.rvm.io | bash -s stable --ruby
Now you need to put a setting in your .bashrc to add rvm to PATH for scripting. Run:
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"' >> ~/.bashrc
Open a new terminal and test rvm.
run
sudo apt-get update
sudo apt-get install build-essential
and then try again.
Hye Guys!!
I got the solution. Actually error is because the information we need for installation is not available at sever define for software & update. I change it to from my local "Server from India" (In my case) to "Main Server".
It's working perfectly for me now :)
I was having the same problem with my install, and then I fully read the details that terminal left once the install was finished.
Try using source /usr/local/rvm/scripts/rvm
Once I did that, the function type rvm | head -1 returned rvm is a function
In my Case i fixed the error by:
rvmsudo rvm install 1.9.3
rvm --default 1.9.3
rvmsudo rvm remove 1.9.3
rvm install 1.9.3
Source
Try disabling repository which appear at 404 sudo apt-get update or viewing logs rvm. The fact is that when you install rvm is trying to update a list of your packages and if you have 404 to go to bed =)
\curl -L https://get.rvm.io | bash -s stable --ruby .
paste this in your terminal window.I used this.It worked for me.for RVM for ruby
\curl -L https://get.rvm.io | bash -s stable --rails .
Use these to install RVM with ruby on rails
For people that know nothing about Linux or are newbies to Linux (like me) those are steps how to solve this (explanation, that was given above, was not that clear for me :) ).
Go to Package Manager, tab Settings, Preferences
In the opened window you'll see Other Software tab or something like that with links to servers. In my case one of these (it's mentioned in the error log that was produced by rvm) was causing errors and was not available (404 errors). I just unchecked it.
run rmv dependencies only when you closed Package Manager, or you'll get error saying that something is locked at the moment.
And everything now is installed successfully! :)
The most common symptom of this problem occurs (as seth2810 hinted at) with non-zero exit codes from an apt-get update command, which rvm requirements expects. You should run this command yourself (with sudo) and check for any problems.
If you have 404s in the output, check that the package sources for the bad URLs are still correct/current. You can remove package sources more easily with sudo apt-get install software-properties-common, followed by sudo add-apt-repository --remove {URL_OF_PROBLEM_PACKAGE_SOURCE} for each failed url.
If you have something hinting at packages with 'unmet dependencies', try sudo apt-get -f install. This command attempts to fix incomplete installs by fetching missing packages and works most of the time. Otherwise... by this point you probably have a more specific error to google for anyway!
I want to install ruby 1.9.3 on Ubuntu without rvm
I run
sudo apt-get install ruby
It's taking ruby 1.8 and ruby 1.9.1.
And if I do
sudo apt-get install ruby 1.9.3 -p XXXX
I am still not able to install ruby. How can I install ruby on Ubuntu?
On Ubuntu 12.04 LTS, I got it to work with the following:
sudo apt-get install ruby 1.9.3
cd /etc/alternatives
sudo ln -sf /usr/bin/ruby1.9.3 ruby
Use the brightbox packages for 1.9.3. You will have to add their repo though but to keep it short here just use their help pages: http://blog.brightbox.co.uk/posts/next-generation-ruby-packages-for-ubuntu
1st approach
Source
http://lenni.info/blog/2012/05/installing-ruby-1-9-3-on-ubuntu-12-04-precise-pengolin/
The new Ubuntu release has just rolled around and with it a slew of new packages. Personally, I'm tracking the development of Ruby quite closely but the default Ruby on Ubuntu ist still the 1.8 series which I can't recommend. Ruby 1.9 has some performance improvements and 1.9.3 in particular a lot of them compared to 1.9.2.
However, as I have elaborated in a previous post getting the Ruby 1.9 series on Ubuntu without using RVM instead of 1.8 isn't all that easy. Please read the post if you are interested in the details.
The short version is: You can get Ruby 1.9.3-p0 by installing the ruby-1.9.1 package. (The package is called 1.9.1 because that is the ABI version.)
If you want to make Ruby 1.9 the default do the following:
sudo apt-get update
sudo apt-get install ruby1.9.1 ruby1.9.1-dev \
rubygems1.9.1 irb1.9.1 ri1.9.1 rdoc1.9.1 \ build-essential libopenssl-ruby1.9.1 libssl-dev zlib1g-dev
sudo update-alternatives --install /usr/bin/ruby ruby /usr/bin/ruby1.9.1 400 \
--slave /usr/share/man/man1/ruby.1.gz ruby.1.gz \
/usr/share/man/man1/ruby1.9.1.1.gz \
--slave /usr/bin/ri ri /usr/bin/ri1.9.1 \
--slave /usr/bin/irb irb /usr/bin/irb1.9.1 \
--slave /usr/bin/rdoc rdoc /usr/bin/rdoc1.9.1
# choose your interpreter
# changes symlinks for /usr/bin/ruby , /usr/bin/gem
# /usr/bin/irb, /usr/bin/ri and man (1) ruby
sudo update-alternatives --config ruby
sudo update-alternatives --config gem
# now try
ruby --version
If you want to make this your exclusive Ruby and get rid of Ruby 1.8 follow the uninstallation instructions.
Edit: I found out today that there also is a package called ruby1.9.3 however that is just a proxy package that doesn't have any files itself and only depends on ruby1.9.1. Aptitude confirms this:
Ruby uses two parallel versioning schemes: the `Ruby library compatibility version' (1.9.1 for this package), which is similar to a library SONAME, and the 'Ruby version' (1.9.3 for this package). Ruby packages in Debian are named using the Ruby library compatibility version, which is sometimes confusing for users who do not follow Ruby development closely. This package depends on the ruby1.9.1 package, and provides compatibility symbolic links from 1.9.3 executables and manual pages to their 1.9.1 counterparts.
There doesn't seem to be a rubygems1.9.3.
2nd approach
Also This link i found useful its very simple and effective.
http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
Compiling from Source is the standard way.
Download source code from Here, Use README file to get instruction.
Another method is apt package manager system.
$ sudo apt-get install ruby1.9.1
Yes, this will install Ruby 1.9.2. It has a ‘library compatibility version’ of 1.9.1, hence the name.
If you install the ‘ruby’ package, you’ll get the older Ruby 1.8.
In my cluster this is really the only solution that worked:

How can I uninstall Ruby 1.9.2dev (2010-07-02) [i486-linux]
on ubuntu?
Need to reinstall - please help
Run the following command from your terminal:
sudo apt-get purge ruby
Usually works well for me.
(caution: this can delete essential system files related to GRUB and other components)
This command should do the trick (provided that you installed it using a dpkg-based packet manager):
aptitude purge ruby
At first find out where ruby is?
then
rm -rf /usr/local/lib/ruby
rm -rf /usr/lib/ruby
rm -f /usr/local/bin/ruby
rm -f /usr/bin/ruby
rm -f /usr/local/bin/irb
rm -f /usr/bin/irb
rm -f /usr/local/bin/gem
rm -f /usr/bin/gem
I have tried many include sudo apt-get purge ruby , sudo apt-get remove ruby and sudo aptitude purge ruby, both with and without '*' at the end. But none of them worked, it may be I've installed more than one version of ruby.
Finally, when I tried sudo apt-get purge ruby1.9(with the version), then it works.
Run the following command on the terminal:
sudo apt-get autoremove ruby
Here is what sudo apt-get purge ruby* removed relating to GRUB for me:
grub-pc
grub-gfxpayload-lists
grub2-common
grub-pc-bin
grub-common
On Lubuntu, I just tried apt-get purge ruby* and as well as removing ruby, it looks like this command tried to remove various things to do with GRUB, which is a bit worrying for next time I want to reboot my computer. I can't yet say if any damage has really been done.
If you used rbenv to install it, you can use
rbenv versions
to see which versions you have installed.
Then, use the uninstall command:
rbenv uninstall [-f|--force] <version>
for example:
rbenv uninstall 2.4.0 # Uninstall Ruby 2.4.0
If you installed Rails, it will be removed, too.
Why you are removing old version of the ruby?
rvm install 2.4.2 // version of ruby u need to insatll
rvm use 2.4.2 --default // set ruby version you want use by default
Using rvm you can install multiple ruby version in the system
Please follow below steps install ruby using rvm
sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm install 2.4.2
rvm use 2.4.2 --default
ruby -v
The installation step will change for different Ubuntu version
For more info,
https://gorails.com/setup/ubuntu/14.04
You can use sudo apt remove ruby
Uninstall the make install software when make uninstall invalid.
make install will create file '.installed.list'
Choose to clean up the files described in .installed.list (need to be careful if you have multiple versions)
Case: ruby2.4 switch to ruby2.3, thinking directly delete all ruby software, and then re-make install 2.3, see: Ruby # Installation Guide
make install -> .installed.list
see .installed.list file, delete all install files.
