You can use gemset for that[0]

You can use gemset for that[0]

[0] RVM: Ruby Version Manager - RVM Gemsets

Alternatively if you specify the version you want in Gemfile and then run bundle install it will use that version for that application. Repeat for the other application.

Also consider vendoring your gems. I'm not sure how to migrate an extant project to use this technique, but when you *create* a project, do "rails new project_name --skip-bundle", cd into the project, and do "bundle install --path vendor --binstubs". Then all the gems will be down under the vendor dir. This will keep your projects well separated for minimal interference, and make it much easier for you to navigate to the source of a given gem if you ever need to see it. You can do this with or without rvm, or any other Ruby-version manager.

You can also kick on global caching in RVM and use Gemsets too if you prefer to keep things at a "global" level.
