This can happen when upgrading to Rails 3.2.

Updating Rubygems should fix this issue.

gem update --system

Hope this helps.

sort of. It fixed the immediate issue... and raised gem install linecache19 -v '0.5.11' Building native extensions. This could take a while...

I had the same problem with dm-active_model-1.2.1 and rails 3.1. Updating rubygems fixed it :) Thanks! This was the error I got: `Invalid gemspec in [[project_dir]/shared/bundle/ruby/1.9.1/specifications/dm-active_model-1.2.1.gemspec]: Illformed requirement ["# 1.2.3"]` – mltsy Apr 12 '12 at 20:45

I still had the errors after updating the rubygem.

Then I ran rvm gemset empty to delete the gems. This fixed it for me.

I had to use "rvmsudo rvm gemset empty" for my globally installed gems, but thanks for the empty tip ! – Martin T. Mar 21 '12 at 09:47
Where do you get the "rvm" or "rvmsudo" commands from? My system doesn't seem to have those. – Brian Knoblauch Aug 09 '12 at 15:44

rvm is a ruby version manager (https://rvm.io/). A utility to have several ruby version installed, with their own gems. Running this command won't help with this problem if you don't already have rvm installed. – Rainer Blessing Aug 09 '12 at 19:59

I had this issue, but all the methods above did not help.

So, I decided to move all the *3.2.0.spec within directory

/usr/local/ruby/lib/ruby/gems/1.9.1/specifications

into another directory, and things are solved.

Command:

sudo mv /usr/local/ruby/lib/ruby/gems/1.9.1/specifications/actionmailer-3.2.0.gemspec <another_dir>

Perform similar commands to other files:

actionpack-3.2.0.gemspec
activemodel-3.2.0.gemspec
activerecord-3.2.0.gemspec
activeresource-3.2.0.gemspec
activesupport-3.2.0.gemspec
newrelic_rpm-3.2.0.gemspec
rails-3.2.0.gemspec
railties-3.2.0.gemspec
