Mongrel users - Feb 2007 - mongrel cluster and local gems loading problem

Hello,

I''m trying to augment the GEM_PATH to load gems from ~/.gem/ using this
at the begging of the rails application config/environment.rb file:

  ENV[''GEM_PATH''] =
File.expand_path(''~/.gem'')

This works fine from within script/console:

  $ script/console
>> require ''pdf/writer''
=> true

But when I try to run:

  mongrel_rails cluster::start

It fails to load the local gem.

I started to dig into the code, and realized that rubygems is
initialized by mongrel_rails before it loads the environment.rb file,
which results in GEM_PATH env. variable being "ignored" (because
rubygem
Gem.path method caches the path on the first use, which is done by
mongrel_rails).  To make this work, I had come to this hack:

  ENV[''GEM_PATH''] =
File.expand_path(''~/.gem'')
  require ''rubygems''; Gem.clear_paths;
Gem.instance_variable_set(:@searcher, nil)

Which clears the internal cache used by rubygems, and forces it to
re-read the GEM_PATH env. variable.

But I don''t fell comfortable using it... is there a better way to do
this?  Like, setting the GEM_PATH from the mongrel cluster config file?


Best regards,
Rui Lopes

PS: require ''rubygems'' is needed just in case we run
script/console from
console.

Hey Rui, I know you were chatting with me on IRC about this.  Did you
ever find a solution?
