Install Ruby On Rails: Quickest way

The quickest way of installing Ruby on Rails with rvm is to run the following commands:

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
\curl -sSL https://get.rvm.io | bash -s stable --rails

Now you will be prompted for password, please enter it. Now let us know what does above command means in short:

gpg: This command will contact a public key server and requests a key associated with the given ID

\curl: It will grab the utility to grab a script file from the rvm website.

-s: This command indicates that the utility should operate in silent mode

Install Ruby On Rails: Long way

Following a long installation procedure, all you need to do is source the rvm scripts by typing:

source ~/.rvm/scripts/rvm

You should now have a full Ruby on Rails environment configured.

Install Ruby On Rails: Specific Version

If you want to install specific version of Ruby On Rails then all you need to do is this:

rvm install ruby_version

Now when this installation is complete, then you can list the versions of Ruby that you want to install by typing command:

rvm list

Switch the versions by typing:

rvm use ruby_version

We can use various Rails versions with each Ruby by creating gemsets and then installing Rails within those using the normal gem commands:

rvm gemset create gemset_name    # create a gemset
rvm ruby_version@gemset_name  # specify Ruby version and our new gemset
gem install rails -v rails_version   # install specific Rails version

Thats all!
