Created Ruby Gemset with specific Rails Version not shown in rvm list

Question

I was following along with the directions here under the section Rails Installation With RVM Gemsets

Per the directions above I created a new rvm gemset:

$ rvm use ruby-2.2.1@rails4.2.1 --create
$ gem install rails

The rails installation was successful, running

$ rails -v

returns rails version 4.2.1 as expected.

Next I ran

$ rvm list

it returns my list of gemsets as:

rvm rubies

  ruby-2.0.0-p247 [ x86_64 ]
  ruby-2.0.0-p598 [ x86_64 ]
  ruby-2.1.1 [ x86_64 ]
  =* ruby-2.2.1 [ x86_64 ]

Why isn't ruby-2.2.1@rails4.2.1 one of my gemsets? I thought I was specifically creating a ruby 2.2.1 gemset with rails 4.2.1, which would then also allow me to keep a separate ruby 2.2.1 gemset with previous versions of rails?

Answer 1

rvm list shows the list of Ruby versions installed, not the gemsets. Try rvm gemset list to see a list of the gemsets.
