    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!

    Thanks for reading the blog.
