I am on the way to install rails. I am using Ubuntu 12.04 LLTS
vipin#vipin-Satellite-C640:~$ uname -a
Linux 3.11.0-18-generic #32~precise1-Ubuntu SMP Thu Feb 20 17:54:21 UTC 2014 i686 i686 i386 GNU/Linux
First I followed this.
but when i tried
rails -v
The program 'ruby' can be found in the following packages:
* ruby1.8
* ruby1.9.1
Try: sudo apt-get install <selected package>
I reinstall ruby by
vipin#vipin-Satellite-C640:~$ rvm reinstall 2.1.0
Now I tried
ruby -v
again same result
vipin#vipin-Satellite-C640:~$ ruby -v
The program 'ruby' can be found in the following packages:
* ruby1.8
* ruby1.9.1
Try: sudo apt-get install <selected package>
I tried to uninstall rvm
vipin#vipin-Satellite-C640:~$ sudo apt-get --purge remove ruby-rvm

I was able to successfully created apps with rails in Ubuntu. Now I updated and upgraded the Kernel.
You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:
sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh
open new terminal and validate environment is clean from old RVM settings (should be no output):
env | grep rvm
if there was output, try to open new terminal, if it does not help then restart your computer.
install RVM:
\curl -L https://get.rvm.io |
bash -s stable --ruby --autolibs=enable --auto-dotfiles
If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanation.

I want to install rvm and geting problem. Here is my command which i run in ubnto 2.10 How can i do this?
root#jaskaran-Vostro-1550:/home/jaskaran# rvm install 2.1.0
The program 'rvm' is currently not installed. You can install it by typing:
apt-get install ruby-rvm
root#jaskaran-Vostro-1550:/home/jaskaran# apt-get install ruby-rvm

E: Unable to locate package ruby-rvm
Use this instead to install RVM:
curl -sSL https://get.rvm.io | bash
You can refer to official RVM Installation Page.
Once RVM is successfully installed, make it available in the current shell:
source /etc/profile.d/rvm.sh
Then you can install the Ruby version you want:
rvm install 2.1.0 to install Ruby version 2.1.0.
You probably want to clean up your environment first just like this post tells you to: Installed Ruby 1.9.3 with RVM but command line doesn't show ruby -v
You can also do this:
sudo apt-get install rvm
next you will have to source the
source /home/username/.rvm/scripts/rvm
after then you can go ahead and install by running
rvm install version
Hope this help another person.
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 using osx 10.8.2 installed ruby 2.0 and....
got this when trying to run "sudo gem install rails"
$ sudo gem install rails
ERROR: Loading command: install (LoadError)
cannot load such file -- openssl
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
I had ruby 1.9.x and rails 3.2.x working alright before
You have to install OpenSSL first and recompile ruby again:
RVM:
rvm pkg install openssl
rvm reinstall ruby-2.0.0-p0 --with-gcc=gcc-4.7 --with-openssl-dir=$rvm_path/usr
If you're using RVM please follow:
$ brew install automake
$ rvm pkg install openssl
$ rvm requirements run
$ rvm reinstall all --force
$ gem install rails
It worked for me.
I had very bad time with this ERROR.
Finally i done with it. There is only Once solution either you are with RVM or without RVM.
Make sure you have installed OpenSSL first BEFORE installing ruby.
RVM
Uninstall rvm
rvm implode
or
rm -rf ~/.rvm
Don’t forget to remove the script calls in your .bashrc and/or .bash_profile (or whatever shell you’re using).
sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs
Then install RVM, post ruby.
OR
rvm pkg install openssl
rvm reinstall ruby-2.0.0-p0 --with-gcc=gcc-4.7 --with-openssl-dir=$rvm_path/usr
WITHOUT RVM
First you should find where Ruby is:
whereis ruby
will list all the places where it exists on your system, then you can remove all them explicitly. Or you can use something like this:
rm -rf /usr/local/lib/ruby
rm -rf /usr/lib/ruby
rm -f /usr/local/bin/ruby
rm -f /usr/bin/ruby
rm -f /usr/local/bin/irb
rm -f /usr/bin/irb
rm -f /usr/local/bin/gem
rm -f /usr/bin/gem
THEN
sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs
apt-get -y update
apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz
tar -xvzf ruby-2.0.0-p247.tar.gz
cd ruby-2.0.0-p247/
./configure --prefix=/usr/local
make
make install
I hope this help you.
I fix this error for ruby 2.1.2 as follow.
rvm pkg install openssl
rvm reinstall ruby-2.1.2 --with-openssl-dir=$rvm_path/usr
On OSX, with rbenv and homebrew, the following worked for me:
brew install openssl
CONFIGURE_OPTS=--with-openssl-dir=$(brew --prefix openssl) rbenv install whatever-ruby-version
This worked for me which is similar to some of the other answers already posted.
rvm pkg install openssl
rvm reinstall all --force
When installing ruby 2.0, it is possible that rubygems 2.0 installation did not complete ok, because of openssl.
Make sure you provide a valid path to the openssl config file; you could:
find . -type f -name "openssl.cnf"
path is usually $HOME/.rvm/usr or $HOME/.rvm/usr/ssl
Then
[sudo] rvm reinstall ruby-2.0.0-p0 --with-openssl-dir=[openssl.cnf path] --verify-downloads 1
Make sure rubygems installation complete successfully.
Might be a better way to fix that path without reinstalling, but this should do it.
Make sure to check out this page on the rvm site: https://rvm.io/packages/openssl/
Running
rvm requirements run
gave me:
Missing required packages: autoconf, automake, libtool, pkg-config, apple-gcc42, readline, libxml2, libxslt, libksba, openssl, sqlite
after brew install autoconf automake ...
I was able to rvm reinstall 2.0.0 without openssl errors
I had the same problem with the same OS version. I use rvm and followed the steps in this command:
$ rvm requirements
Following those instructions, I ran:
$ brew update
$ brew tap homebrew/dupes
$ brew install bash curl git
$ brew install autoconf automake apple-gcc42 libtool pkg-config openssl readline libyaml sqlite libxml2 libxslt libksba
I had the same problem earlier, tried all of the snippets about and none of them worked out. After looking around for a bit the following worked for me:
$ rvm remove 2.0.0 # get rid of unsuccessful installation
$ rvm get head --autolibs=3 # get the latest RVM and build required libs
$ rvm requirements # just in case, install all other required stuff
$ rvm install ruby-2.0.0
$ rvm --default use ruby-2.0.0
What does rvm get head --autolibs=3 do exactly? I'm guess it automatically downloads dependencies, but I was hoping for a clear answer.
I encountered the same openssl error on Fedora when trying to use gem install <package>. It seems you need to install additional packages with yum/dnf
sudo dnf install rubygems rubygem-bundler ruby-devel mariadb-devel
After running the above command, gem install <package> should now work.
just went through the same problem. Takes a bit time but, upgrading openssl with
brew upgrade openssl#1.1
worked for me. Version might be different in the future, type brew install openssl to see which version you can upgrade to. I hope it helps.
If you have libssl1.1, your problem may be that these older versions of ruby (2.4 is the cutoff) are only compatible with libssl1.0.
For debian/ubuntu, please ensure that apt-get install libssl1.0-dev succeeds.
If you are using ruby-install, it will take the same openssl argument as rvm:
ruby-install ruby-2.0.0-p247 -- --with-openssl-dir=/usr/local/opt/openssl
is there any way to install Ruby 1.9.2 or 1.8.7 + Rails 3 on my debian squeeze?
You probably don't want to use RVM on a production machine. Its $PATH magic will break in non-obvious places (e.g. cron jobs), and you'll be up a creek.
You could simply build from sources and use checkinstall to create a .deb for yourself. Here's a tutorial for Ubuntu that should translate pretty well into debian.
First install rubygems, I think it's the only Debian package. Then (as Ruby gems):
rvm (install with it ruby 1.9.2, or Ruby version you want)
bundler
rails
And then you can manage application gems with Bundler.
Have you looked at railsready-debian-lenny (it is claimed to work on Squeeze too)? Don't forget to install dependencies pointed in readme.md
The steps below outlines installing Ruby On Rails as a normal user.
Check first if the user has sudo rights. To do this try executing a simple command
$sudo ls -a
[sudo] password for unlimit:
unlimit is not in the sudoers file. This incident will be reported.
If you see a message like above, you will need to add the user to the sudoer file, this can be done by
$echo 'unlimit ALL=(ALL) ALL' >> /etc/sudoers
Check if you have ruby installed. Execute the command below
$ruby -v
-[bash]: ruby:command not found
If you see something like this, this means ruby is not installed. Install it
$sudo apt-get install ruby
Install additional libraries
$sudo apt-get install build-essential
$sudo apt-get install curl
$sudo apt-get install libssl-dev
Install rvm
$curl -L get.rvm.io | bash -s stable
Set the rvm path
$source $HOME/.rvm/scripts/rvm
You should add this to the .bashrc file.
Fetch the latest rvm and reload it
$rvm get head && rvm reload
Install ruby 1.9.3
$rvm install 1.9.3 --with-openssl-dir=$HOME/.rvm.usr
I needed to install the readline lib
$sudo apt-get install libreadline-dev
Get the rails gem
$gem install rails -v 3.2.3
Check if you have rails
$rails -v
Rails 3.2.3
Get the readline package
$rvm pkg install readline
Get sqlite3
$sudo apt-get install sqlite3 libsqlite3-dev
You are all set to create your first rails app
$rails new app HelloWorld
You can find more info http://unlimit.in/installing-ruby-on-rails-on-debian.html
The best way to install Ruby and any Gems you like is with RVM. It will compile the latest version of Ruby for you and give you tools to manage gemsets.
Relying on the distribution's packages is usually a bad idea, because they are typically out-of-date.
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.
