I’m having an issue with RVM. In general I use project specific gemsets; however, recently when I install a gem into the @global gemset, it is not available when I’m working in a particular project. Here is an example where I was trying to install the hpricot gem. This is right after installing the gem and starting a fresh shell.

$ rvm use ruby-1.9.2
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180

$ gem list

*** LOCAL GEMS ***

bundler (1.0.12)
hpricot (0.8.4)
rake (0.8.7)

$ rvm use ruby-1.9.2@myproject-gems
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180 with gemset myproject-gems

$ gem list | grep hpricot

$ rvm info

Any ideas why hpricot would not be available inside of the project gemset? I did have the same issue with bundler as well, but ended up installing it again in the gemset.

Thanks..

    The problem here is that I wasn’t using the @global gemset when installing hpricot gem the first time.

    There is a difference between the interpreter’s default gemset and the @global gemset for that interpreter.

    So you can achieve the desired result by 

    $ rvm use ruby-1.9.2@global
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180 with gemset global

$ gem install validation_refelection
Fetching: validation_reflection-1.0.0.gem (100%)
Successfully installed validation_reflection-1.0.0
1 gem installed
Installing ri documentation for validation_reflection-1.0.0...
Installing RDoc documentation for validation_reflection-1.0.0...

$ rvm use ruby-1.9.2@myproject-gems
Using /home/bshaver/.rvm/gems/ruby-1.9.2-p180 with gemset myproject-gems

$ gem list | grep validation_reflection
validation_reflection (1.0.0)

    And the gem is available to the project as desired.
