Personally I only install Bundler and a few other gems which provide command line utilities I use. The rest is handled with Bundler on a per-project basis.

I recently blogged about my setup here: http://jimeh.me/blog/2011/11/01/my-ruby-development-environment/

Really guys, why aren’t ruby, rvm, rubygems, and bundler on speaking terms with each other to straighten this out?

Why is rubygems unaware of Gemfile? Shouldn’t that be part of its domain?

Why do we still need “bundle exec” in front of everything? There was a proposal from RVM to manage that in the presence of a Gemfile, but it was rejected. (I think rbenv has a plugin to do that).

I know I’m just ranting, but this whole gems thing shouldn’t be so clumsy…

Would it make sense for RubyGems or Bundler to cache the mapping of require -> gem path somewhere on disk so it wouldn’t have to scan for them every time?

Or if you’re on OSX:

gem list | cut -f1 -d ” ” | xargs gem uninstall -aIx

@deepfryed no, that won’t really help. Just using the `bundle` bin stub will evaluate every gemspec on your system.

if you’re using bundler, can’t you just do a bundle install –standalone and only require the gems you use ?

Cleanup will still leave some gems installed. I have this aliased to gem_purge in my console.

gem list | cut -d” ” -f1 | xargs gem uninstall -aIx

The most extreme version of this approach would be to leave your system gems empty except for Bundler, and use `bundle install –path vendor/bundle` in each project — that way only gems for the project will be loaded etc.
