Invalid date format specification in gemspec

I am getting the following error when I try to use gems in windows, and I also referred to this stackoverflow post and updated rubygems and rails. But nothing could solve the problem.

The following is the complete error,

    D:\>gem env

The ultimate solution is this:

Search "spec" files in your Ruby directory: *C:\Ruby187\lib\ruby\gems\1.8\specifications*

If a gemspec file contains something like this: s.date = %q{2011-10-13 00:00:00.000000000Z} Then delete the 00:00:00.000000000Z part: s.date = %q{2011-10-13}

After saving those gemspec files, the problem is solved.

None of these solutions worked for me. To fix it, I removed all the content of the mentioned directory (some/path/to/specification/) then I installed the gems I need (actually, Bundler then bundle install).

I have fixed this issue by upgrading my RubyGems to 1.8.10 with

gem update --system

Edit: You can also try (as suggested by ZeissS)

gem install rubygems-update
update_rubygems
