I'm currently trying to run 'bundle install' to install a git based gem using a Gemfile and consequently use ruby/ other ruby commands without bundler with the latest version of RVM (1.14.3).

I believe the cause of the issue is that bundler is installing the git gem into .rvm/gems/ruby-1.9.3-p194@something/bundler/gems while all other gems are installed into .rvm/gems/ruby-1.9.3-p194@something/gems. As a result, 'bundle list' shows the gem but 'gem list' does not.

Any thoughts here? I'd really prefer not to use bundle to execute everything.

Bundler is for bundling gems with applications. It doesn't make sense to use it for system gems. Unfortunately, the non-bundler gem system offers no direct way to install git-based gems (I actually asked a question about this previously, see Is it possible to directly install a gem from a git repository?). Instead, you have to do it manually in three steps:

  1. Clone the gem repo (this is assuming a github repository, but it will work for a repository hosted anywhere, just substitute the right git repo location).

    git clone git://github.com/user/gem.git

  2. Go to the cloned gem repo directory and build the gem (this will also check for dependencies and warn you if the install failed because of a missing dependency -- in that case just install the dependencies and try again).

    rake gem

    Or if that doesn't work:

    gem build gem.gemspec

  3. This should have created a file with a name like pkg/gem-1.2.3.gem (sometimes it will build in the pkg directory like this, sometimes it will build in the gem repo root directory). You can now install it.

    gem install pkg/gem-1.2.3.gem

  • I did more research and found the comment in http://stackoverflow.com/questions/3175511/why-is-bundler-not-installing-gems-stored-in-get-repo-properly which references http://yehudakatz.com/2010/04/12/some-of-the-problems-bundler-solves/ -- I recognize that gem and bundler are different but I'm really looking for way to make the gem/ bundler/gem dirs be the same dirs so gem can just use the bundler installed git gems? – Michael Wasser Jun 30 '12 at 20:30
