Invalid gemspec error while running compass in ruby

问题

I receive the following error when running a new compass project in OSX 10.7.3.

Invalid gemspec in [/Library/Ruby/Gems/1.8/specifications/multipart-post-1.1.5.gemspec]:           invalid date format in specification: "2012-02-13 00:00:00.000000000Z"

I have tried running sudo gem update --system to cure the problem but I get the same error when doing so.

回答1:

Try this

gem install rubygems-update
update_rubygems
