Sometimes, when running a rake task, RubyGems 1.8.5 raises an error:
rake aborted!
undefined method `specifications' for "/usr/lib/ruby/gems/1.8":String
This has been fixed since May 31 but is still not available as a new RubyGems version.
Either wait for a new version to eventually come out, downgrade to some really old version (1.6.2 works for some) or apply the fix Show archive.org snapshot manually:
- Find your rubygems.rb -- mine was located at
/usr/local/lib/site_ruby/1.8/rubygems.rb - Modify the
self.each_load_pathmethod according to the path. Mine now looks like this:
def self.each_load_path(partials)
partials.each do |gp|
base = File.basename gp
specfn = File.join(dir, "specifications", "#{base}.gemspec")
if File.exists? specfn
spec = eval(File.read(specfn))
spec.require_paths.each do |rp|
yield File.join(gp,rp)
end
else
filename = File.join(gp, 'lib')
yield(filename) if File.exists? filename
end
end
end - Also, I needed to change a second appearance of “
gemdir.add(load_path).expand_path” in line 261 to “result << load_path” for it to work (which is probably covered by some other fix commit).
I bet there is a semi-automated way to get a patch from the Github repository that you can apply on your rubygems.rb but I don't care enough to toy around with git format-patch. If you do, let me know.
