Invalid date format specification in gemspec

问题:

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

回答1:

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

回答2:

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.

回答3:

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).

回答4:

In addition to running gem update --system I used gem install <gem with bad gemspec> on each of the item gem env reported as bad. This cleaned up the errors on my machine.

回答5:

As Michael said in the comment:

gem pristine --all

回答6:

Had the same problem when trying to install a GEM on Ubuntu 11.10.

Invalid gemspec in [/var/lib/gems/1.8/specifications/svn2git-2.1.2.gemspec]: invalid date format in specification: "2011-12-28 00:00:00.000000000Z"

The above options did not work for me. gem env reported the following:

RubyGems Environment:
  - RUBYGEMS VERSION: 1.7.2
  - RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]

So I presumed this problem was due to the fact I required a newer version of RubyGems installed.

Issuing gem update --system yeilded the following warning:

ERROR:  gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories.
If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian.

However I was finally able to update rubygems to 1.8.15 by issuing:

sudo gem install rubygems-update && update_rubygems

Everything worked after that, good luck! :)

Invalid gemspec in [/var/lib/gems/1.8/specifications/chronic-0.6.4.gemspec]: invalid date format in specification: "2011-09-09 00:00:00.000000000Z"

The simple fix to such kind of problem is to navigate to the file.. for eg.

Step 1. cd /var/lib/gems/1.8/specifications
step 2. open the file(chronic-0.6.4.gemspec) in editor of ur choice... (gedit chronic-0.6.4.gemspec)
step 3. change the s.date = %q{2011-10-13 00:00:00.000000000Z} to s.date = %q{2011-10-13}

Cheers :)

回答8:

I just had the same problem on my ubuntu after upgrading to 10.10. None of the above worked for me. I had to install the update_rubygems script from http://rubygems.org/pages/download and run it once. Afterwords everything worked.

回答9:

I have fixed this issue 'invalid date formate specification' by, changing the corresponding line in D:/RailsInstaller/Ruby1.8.7/lib/ruby/gems/1.8/specifications/tilt-1.3.3.gemspec by putting s.date =Time.now instead of s.date = "2011-08-25 00:00:00.000000000Z" The same can be use the other files too.

回答10:

I've too many gems to fix one by one, and try both update_rubygems and gem pristine --all still no luck.

So I use rvm clear gemset to remove all gems with wrong gemspec. Execute bundle install to reinstall all the gems, and Viola!

回答11:

cd vendor/bundle/ruby/1.9.x/specifications
sed -i 's/ 00\:00\:00.000000000Z//g' *

回答12:

Solved by running gem update --system then gem update.

回答13:

The various solutions noted in these answers did not work for me. What did work was re-installing the specific versions of the offending gem's. In your case that would of looked like:

gem install tilt   -v 1.3.3
gem install execjs -v 1.2.4
gem install temple -v 0.3.3
gem install guard  -v 0.6.3
gem install guard-livereload -v 0.3.1
gem install rack-cache -v 1.0.3

I think that gem pristine xxx yyy zzz or gem pristine --all might not be going out always (ever?) to the gem repositories whereas gem install xxx -v v.r.m does.

Anyway, re-installing the offending versions of the gems worked for me, although it was tedious...

回答14:

rvm gemset clear and then bundle install worked for me!

回答15:

"gem install rubygems-update", "update_rubygems", then "gem pristine --all" is the combination that solved the problem for me after none of the previously listed ones worked.

回答16:

In my case, the referenced gem versions weren't even installed. I had those gems, but not the versions who's gemspecs were causing the error. So, I just deleted each of the /path/to/specifications/offending-X.Y.ZZ.gemspec files.

回答17:

This is not really an answer but if somebody feels like digging more I found this gemspec spec here: http://rubygems.rubyforge.org/rubygems-update/Gem/Specification.html (scroll down to date=date() and click to show source):

@date = case date
when String then
  if %r\A(\d{4})-(\d{2})-(\d{2})\Z/ =~ date then
    Time.utc($1.to_i, $2.to_i, $3.to_i)
  else
    raise(Gem::InvalidSpecificationException,
          "invalid date format in specification: #{date.inspect}")
  end
when Time, Date then
  Time.utc(date.year, date.month, date.day)
else
  TODAY
end

So I guess this is the code that parses that gemspec, and it just looks like the date format that are in the files that show errors don't conform to this.

What I did was to just manually fix those offending gemspecs as suggested above (changing the dates to "yyyy-mm-dd", it works for me.

All the rubygem specs I had that had this problem also has a line

s.rubygems_version = %q{1.3.5}

So I'm guessing these are just old gems? And what's with those %q{...} anyway?

回答18:

If you had this error on Ubuntu 11.04 my solution was the following command lines:

$ sudo apt-get install ruby1.9.1

After doing this you will not get the date error.
