Invalid gemspec

[josegrad]

Hi, I'm trying to use carmen-rails in one of my apps and I get the next error when starting the rails server.

Invalid gemspec in [/Users/elmaco/.rvm/gems/ruby-1.9.2-p0/specifications/carmen-1.0.0.beta2.gemspec]: Illformed requirement ["#Syck::DefaultKey:0x00000109445f70 2.6.1"]

Could not find carmen-1.0.0.beta2 in any of the sources

I added gem 'carmen-rails' to gemfile and bundle install shows:
Installing carmen (1.0.0.beta2)
Using carmen-rails (1.0.0.beta3)

Any hints?

What version of Rubygems are you using?

1.6.2

I think you need to update to Rubygems 1.8.x in order to fix this. You'll then need to manually delete the gemspec at /Users/elmaco/.rvm/gems/ruby-1.9.2-p0/specifications/carmen-1.0.0.beta2.gemspec and run bundle again.

This is related to how different versions of Rubygems deal with Yaml, and unfortunately there isn't a cleaner fix. The good news is updating Rubygems should prevent this from happening again.

Ok, thanks for the quick reply!
