  5. Aaron Seliger said

    Thanks Olivier, this has been most helpful. Good high level overview to let me know what I should have on my radar to dig into further. Groovy!

    Important note: you should not use 'rvm get head' to update RVM but instead go for 'rvm get stable'.

    The reason: 'get head' fetches the current master branch on RVM's GitHub repository, whereas 'get stable' fetches the stable branch. And by all means, you should only use the stable releases. It doesn't mean RVM will explode in your face, but there's a much higher chance if you're using 'HEAD'.

    My bad.

    Very clear tutorial Olivier. The diagram around 4:30 .. Ruby Versions > Gemsets (global, projects) ... helped me to understand structure and use. Thanks!

    @beazler I'm glad it helped. It took me a while to understand the underpinnings of RVM myself and I remembered it was often a stumbling block for people.

  15. Alexandr Zavalny said

    Why use gemsets anyway? Why not just to install all gems to global? Is it because of gem versions? Like use one gem version in one app, and another one in second app?

    Olivier Lacan said

    Alexandr, yes it's because of conflicts between different applications which use the same gems but different versions of them. This is largely solved by using Bundler nowadays so Gemsets aren't nearly as important as they used to be. You can read more about RVM & Bundler here: http://rvm.io/integration/bundler
