undefined method version error

[npcventures]

Hi, I was attempting to follow the doc here (http://jekyllrb.com/docs/continuous-integration/) and found an interesting error when running bundle exec htmlproof ./_site.

/Users/me/.rbenv/versions/1.9.3-p547/lib/ruby/gems/1.9.1/gems/html-proofer-1.1.5/bin/htmlproof:11:in `block in <top (required)>': undefined method `version' for nil:NilClass (NoMethodError)
    from /Users/me/.rbenv/versions/1.9.3-p547/lib/ruby/gems/1.9.1/gems/mercenary-0.3.4/lib/mercenary.rb:21:in `program'
    from /Users/me/.rbenv/versions/1.9.3-p547/lib/ruby/gems/1.9.1/gems/html-proofer-1.1.5/bin/htmlproof:10:in `<top (required)>'
    from /Users/me/.rbenv/versions/1.9.3-p547/bin/htmlproof:23:in `load'
    from /Users/me/.rbenv/versions/1.9.3-p547/bin/htmlproof:23:in `<main>'

This happens to me on both CI (Shippable, Ubuntu 12.04) as well as a local environment (OSX 10.9.2, ruby 1.9.3p547). I installed the gem through bundle install.

A quick fix is commenting out line 11 in bin/htmlproof:

p.version Gem::Specification::load(File.join(File.dirname(__FILE__), "..", "html-proofer.gemspec")).version

This suggests that the "html-proofer.gemspec" file is missing, and indeed it is:

$ cd /Users/me/.rbenv/versions/1.9.3-p547/lib/ruby/gems/1.9.1/gems/html-proofer-1.1.5/
$ ls -l
drwxr-xr-x  3 me  staff   102 Aug  7 22:38 bin
drwxr-xr-x  3 me  staff   102 Aug  7 22:23 lib
$ curl -O https://raw.githubusercontent.com/gjtorikian/html-proofer/master/html-proofer.gemspec

I checked and the issue is not there in version 1.1.4, which seems to download all the files in the repository, not just the bin and lib directories. As a result, the issue may stem from 88f6572.

Thank you for writing the gem - it has helped me find many interesting link errors.

Ughhhhhh It's definitely from 88f6572. Reverting and shipping another bugfix update. Thanks!
