Install Ruby on Rails using rvm on Ubuntu 12.04 - ruby-on-rails

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.

ruby install rvm not working

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
Reading package lists... Done
Building dependency tree
Reading state information... Done
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.

Installing Ruby on Rails on Linux mint?

When I used "sudo apt-get install ruby-full build-essential" in the terminal I got this:
$ sudo apt-get install ruby-full build-essential
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/packages.medibuntu.org_dists_quantal_non-free_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
Can anybody tell me how can I install Ruby on Rails in my Linux Mint machine?
I think you don't need features of rvm. You just want to install ruby easy, fast and without troubles, right? Good news to you. We got an alternative to rvm. It's called rbenv. You can find an installation guide here.(don't skip ruby-build, it is necessary!).
And yes, follow ubuntu instructions since Mint is build on it (though there's debian-based version but I suppose you use ubuntu-based one).
I installed yesterday Mint 16 and rbenv on it. Works fine.
PS: don't forget to sudo apt-get install build-essential first.
I actually use Mint on my main development system. I'd also recommend using RVM to manage all your Ruby and Rails installation/versions. The command to install it is:
\curl -L https://get.rvm.io | bash -s stable
You can also append --ruby and --rails to get (I believe) the most recent versions of the two of them. I'd recommend not using apt-get for installing Ruby, as I've noticed that it can be out of date and/or lead to strange errors like those that you're seeing. You can get more information from the RVM website. I really enjoy using Mint, so I hope that helps.
Use rvm to install Ruby then simply install rails gem , but before that fix your repository related problem.
sudo rm -rf /var/log/apt/list
sudo apt-get update
sudo apt-get upgrade
Then install rvm see rvm.io for installation info
If you are new want to setup everything from start then see this blog post
https://www.computersnyou.com/4235
Use rbenv
instead, use this link DigitalOcean since mint is an ubuntu based distro, it will work.

Can't install Ruby on Rails with RVM on Ubuntu 13.04

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!

Install RoR on debian Squeeze

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 on ubuntu?

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.
