…somehow they managed to f’**k it up, anyway. Because, out of the box
fails with a remarkably stupid and confusing error message:
Freezing to the gems for Rails 1.2.3 ERROR: While executing gem ... (Gem::Exception) Cannot load gem at [/Library/Ruby/Gems/1.8/cache/activesupport-1.4.2.gem] in /Users/jan/Documents/ruby/railsdocs/app/vendor/rails
Thats because actually the gems are located in a different place:
gem environment RubyGems Environment: - VERSION: 0.9.4 (0.9.4) - INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8 - GEM PATH: - /System/Library/Frameworks/Ruby.framework/ Versions/1.8/usr/lib/ruby/gems/1.8 - /Library/Ruby/Gems/1.8 - REMOTE SOURCES: - http://gems.rubyforge.org
The factory delivered gems are stored in the first path, but rails:freeze:gems doesn’t seem to like multiple gem paths.
Mind you, the fix is easy: A simple
sudo gem update rails -y
bumps rails to 1.2.5, the gems are downloaded to /Library/Ruby/Gems/1.8 and rails:freeze:gems works like a charm afterwards.
I’m still not 100% sure what causes this. A simple gem unpack (as done by the rake task in form of a Gemrunner call) fails, as it simply looks in the wrong place. What worries me is that all normal requiring seems to work, so I can only assume the the gem require logic and the lookup logic of the gem tool itself somehow are different. That’s not clever.
So, is rubygems simply not capable to have multiple gem storages? Is it probably only hacked by Apple people to do so at least for the require logic?
So much to explore, so little time.
