When first started, I installed Rails with rbenv and, through time, created a few apps. I have not had to touch rbenv, never had a problem, yet never had a chance to get to know it.

I recently decided to run through the "Learn Ruby on Rails" tutorial by Daniel Kehoe. In his chapters dealing with installation, he has us download RVM with a project-specific gemset using the following command:

$ rvm use ruby-2.1.1@learn-rails --create
$ gem install rails

Will I still be able to download the specific gemset using rbenv instead? If so, what is the command and how would I go about this?

On a side note, are there any great beginner tutorials for using rbenv?

  • "is there any great beginner tutorials for using rbenv?". Yes. Read [the instructions](https://github.com/sstephenson/rbenv). It's a very nicely thought out tool that is easy to understand. – the Tin Man Oct 08 '14 at 20:20
  • Also, like all programs, rbenv has upgrades. Be sure to periodically run `git pull` from inside ~/.rbenv to pull in changes. – the Tin Man Oct 08 '14 at 20:23

You shouldn't install RVM and rbenv side-by-side. They can interfere with one another. What I would recommend doing instead is ignoring the RVM + gemset section and continuing on with the guide using rbenv.

Concurring with Ryan Bigg's answer: indeed, see https://github.com/sstephenson/rbenv#installation:

Compatibility note: rbenv is incompatible with RVM. Please make sure to fully uninstall RVM and remove any references to it from your shell initialization files before installing rbenv.

And if you want to use gemsets with rbenv, see https://github.com/jf/rbenv-gemset
