I'm getting this error from a fresh install of ruby 1.9.2 with default rubygems & updated rubygems (and debian squeeze ruby 1.8.7 & default rubygems)

Here the complete log:
ruby 1.9: http://pastie.org/2739968
ruby 1.8: http://pastie.org/2739826

Everything worked good before a "bundle update"
Searched 2hours this error without result

Thanks in advance

    Is this still happening?

    I'm having (what I think is) a similar problem, whenever I run any gem commands. I'm working on writing my first gem, and this started happening after I installed it.

    Here's the output: http://pastie.org/4659979

    Hey Chris.

    Sounds like you've got a corrupted gem spec, probably from the gem you're working on. My guess is that it's related to an old version of RubyGems in the old version of Ruby you're using. Whatever the gem name is, you should be able to cd into your gems dir (somewhere in ~/.rvm), kill its specifications/ and cache/ folders, and start over.

    The gem spec probably needs ["lib"] instead for some entry in there…you could also just jump into the specifications/ dir and manually edit it to fix it (and then rebuild your gem so this doesn't happen anymore).

    Overall this is a pretty gross bug…I'd try updating RubyGems once you're done, hopefully this won't happen in later versions.

    Thanks Nick! Deleting the files in cache/ and specifications/ fixed it. I'll be more careful with my gemspecs going forward.
