ruby-clean-css's Issues

NoMethodError: undefined method `new'

I just deleted and recloned my Rails app. I've been using ruby-clean-css for CSS minification for a while now and it's all been great, but now all of a sudden I'm getting this:

% bundle exec rake assets:precompile RAILS_ENV=production
rake aborted!

gem "ruby-clean-css"

execjs support

So after doing a bunch of research, clean-css is great. I'm currently using this gem in voltframework - https://github.com/voltrb/volt ) My users on windows are having trouble installing libv8, and it would be great if the windows users could use a different JS runtime. I'm not sure if there's libv8 specific features your using, but if your interested in adding execjs support, let me know and maybe I or someone else from the volt community could help.

Thanks!

uninitialized constant RubyCleanCSS::Exports::Http::OpenSSL (V8::Error)

I'm getting this error, probably with RubyCleanCSS::Compressor#compress:

/home/user/.gem/ruby/2.2.0/gems/ruby-clean-css-1.0.0/lib/ruby-clean-css/exports.rb:202:in `block in initialize': uninitialized constant RubyCleanCSS::Exports::Http::OpenSSL (V8::Error)

        from ../_tools/compress-css.rb:26:in `main'
        from ../_tools/compress-css.rb:33:in `<main>'

But adding require 'openssl' to ruby-clean-css/exports.rb fixes it. I'm using ruby 2.0, 2.1 and 2.2.
