Invalid gemspec because of the date format in specification

When I include a gem that I made, thanks to Bundler (version 1.0.12), in a Gemfile and then I try to bundle or to rake just like that:

$ rake

I've got this error message:

Invalid gemspec in [/Users/zagzag/.rvm/gems/ruby-1.9.2-p180@foobar/specifications/myplugin-1.0.0.gemspec]: invalid date format in specification: "2011-04-21 00:00:00.000000000Z"

I'm on the last Mac OS X (10.6.4), with:

$ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.4.0]

and:

$ gem -v
Invalid gemspec in [/Users/zagzag/.rvm/gems/ruby-1.9.2-p180@foobar/specifications/myplugin-1.0.0.gemspec]: invalid date format in specification: "2011-04-21 00:00:00.000000000Z"
1.7.2

I really don't see how to solve this issue. Thanks for any ideas.

Solution 1:

Here is the way I fix the "invalid date format in specification" error:

1.) Go to the specifications folder located at:

/usr/local/lib/ruby/gems/1.8/specifications/

2.) Find the spec that is causing the problem.

3.) Change s.date = %q{2011-05-21 00:00:00.000000000Z} to s.date = %q{2011-05-21}

That's a WIN for me! Good Luck

Solution 2:

Here is the command to fix this for all your gems:

perl -p -i -e 's/ 00:00:00.000000000Z//' ~/gems/specifications/*.gemspec

It converts s.date = %q{2011-05-21 00:00:00.000000000Z} to s.date = %q{2011-05-21} and should fix your issue.

Solution 3:

Please notice the comment from Damian Nowak. These commands do possibly mess up your rubygems!

On Ubuntu 11.10 the following solved this error:

sudo gem install rubygems-update
sudo update_rubygems

The following may work on some systems but not on Debian based:

sudo gem update --system

Solution 4:

You may upgraded your gem. To fix this you can edit the gemspecfile directly - from

2011-04-21 00:00:00.000000000Z

YYYY-MM-DD

Or upgrade your rails also

sudo gem update rails

It will fix the issue.

Solution 5:

Don't specify the time... just the date. 2011-04-21 should work fine.
