Hi all, Sorry, a bit of a cross-post here, because I’m not sure if this is a Rails issue or a gems issue. The problem is that I’ve got sys-admin installed, just not as a gem, and that’s causing a problem. First, some config info: RubyGems Environment: - RUBYGEMS VERSION: 1.3.0 - RUBY VERSION: 1.8.6 (2008-03-03 patchlevel 114) [i386-mswin32\_80] - INSTALLATION DIRECTORY: C:/ruby/lib/ruby/gems/1.8 - RUBY EXECUTABLE: C:/ruby/bin/ruby.exe - EXECUTABLE DIRECTORY: C:/ruby/bin - RUBYGEMS PLATFORMS: - ruby - x86-mswin32-80 - GEM PATHS: - C:/ruby/lib/ruby/gems/1.8 - C:/Documents and Settings/djberge/.gem/ruby/1.8 - GEM CONFIGURATION: - :update\_sources =\> true - :verbose =\> true - :benchmark =\> false - :backtrace =\> false - :bulk\_threshold =\> 1000 - REMOTE SOURCES: - [http://gems.rubyforge.org/](http://gems.rubyforge.org/) irb(main):001:0\> require ‘sys/admin’ =\> true However, if I try to fire up Rails I get this: C:/ruby/lib/ruby/site\_ruby/1.8/rubygems.rb:628:in `report_activate_error': Could not find RubyGem sys-admin (>= 0) (Gem::LoadError) from C:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:139:in `activate’ from C:/ruby/lib/ruby/site\_ruby/1.8/rubygems.rb:163:in `activate' from C:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:162:in `each’ from C:/ruby/lib/ruby/site\_ruby/1.8/rubygems.rb:162:in `activate' from C:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 31:in `require’ from C:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/ active\_support/dependencies.rb:510:in `require' from C:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/ active_support/dependencies.rb:355:in `new\_constants\_in’ from C:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/ active\_support/dependencies.rb:510:in `require' ... 12 levels... from C:/ruby/lib/ruby/gems/1.8/gems/rails-2.1.1/lib/commands/ server.rb:39 from C:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 27:in `gem\_original\_require’ from C:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb: 27:in `require’ from script/server:3 What’s happening here? Problem with my setup or environment? Or a problem with Rails? Thanks, Dan ---

Hey Dan, Have you tried modifying the load path with the ‘gem’ command? It seems to be able to map the path to the gem, which makes me think that’s not the issue, but it’s worth trying perhaps; maybe something activesupport is doing is getting in the way. Worst case, if it works you’re on the path to a real fix. 🙂 -Erik ---

Problem with my setup or environment? Or a > problem with Rails? Ok, I think I’ve narrow this down a bit. The background to this is that I’ve installed the library called “win32-file” via rubygems. That library has a dependency on win32-file-stat, which in turn has a dependency on windows-pr, which in turn has a dependency on windows- api which in turn has a dependency on win32-api. You with me so far? It’s the win32-api gem (or lack thereof) that’s ultimately causing the issue. You see, I’m using a custom built Ruby using VC++ 8.0, so I had to uninstall win32-api (because the current binary gem I have out there is incompatible with my runtime), so that rubygems defaults to the win32-api I’ve built by hand and installed in Ruby’s sitelibdir. At least that’s what I thought it would do. And here’s where it seems to get confused. Because one of the dependencies itself has a dependency on win32-api, but I’ve removed the win32-api gem, it dies instead of resorting to gem\_original\_require as a last ditch effort. I _think_ this can be resolved by rescuing Gem::LoadError in custom\_require.rb, but I’m still deciding how to proceed. If anyone has any suggestion in the meantime, I’m all ears. Regards, Dan
