Install Rails 3.1.3 and set up in Linux

Install RVM

If you are not already installed RVM install from here:
https://rvm.beginrescueend.com/rvm/install/

If you already have rvm installed, update it to the latest version.

$ rvm get latest
$ rvm reload
$ rvm -v

Create a Rails 3.1.3 Gemset

Create a default Rails 3.1.3 gemset. It’s advisable to create a new gemset for each application you build. But to get started, create just one new Rails 3.1.3 gemset as your default.

$ rvm ruby-1.9.2-p290@rails313 --create --default

To see a list of the gemsets you have installed:

$ rvm gemset list

And see a list of the gems included with the standard Ruby installation:

$ gem list

$ rvm list gemsets

rvm gemsets

ruby-1.9.2-p290 [ i386 ]
ruby-1.9.2-p290@global [ i386 ]
=> ruby-1.9.2-p290@rails313 [ i386 ]

Make sure you are using the newest version of Rake before you install Rails 3.1.3.

$ gem update rake
$ rake --version

Install Rails

$ gem install rails -v "3.1.3"
