rvm & duplicate environment variables (rubymotion)

Question

I think I have a gem installed twice but I don't know how to uninstall one of them. When I try to build my rubymotion project I get these warnings:

/Users/pachun/.rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.2.1/lib/Bundler.rb:12: warning: already initialized constant ORIGINAL_ENV
/Users/pachun/.rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.2.1/lib/Bundler.rb:64: warning: already initialized constant WINDOWS
/Users/pachun/.rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.2.1/lib/Bundler.rb:65: warning: already initialized constant FREEBSD
/Users/pachun/.rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.2.1/lib/Bundler.rb:66: warning: already initialized constant NULL

And regular builds still work, but I think this is causing my test suite (frank cucumber) to fail.

How can I fix this? Thanks

Answer 1

The easiest way to remove all gems and reinstall using rvm is do this:

rvm gemset empty <gemset name>
bundle

Instead of doing that, I would recommend you make a .rvmrc file and put the following:

rvm use 1.9.3@projectname --create

Save the file to your project folder and then cd out and back in to the folder, answering "Y" to the question of whether to load the .rvmrc file. This will switch you to a new (empty) gemset and you can re-run bundle.
