I have a project where flay is failing on Rails ERb files.

So I added

gem 'flay-actionpack'

to Gemfile, but it still failed to parse ERb files.

Investigating with ruby -d, Bundler appears to be trying to load:

• 'flay-actionpack'
• 'flay/actionpack'

But the actual file is 'flay_actionpack.rb' so neither of those is going to work.

The code in Bundler responsible for this is: https://github.com/rubygems/bundler/blob/master/lib/bundler/runtime.rb#L65-L94

Clearly it must have worked at some point in the past, so my guess is that perhaps Bundler changed its mind on what separators it was going to permit?

While attempting to use this gem on a project I kept receiving a wrong number of arguments error, upon ivestigation I suspect the culprit to be: https://github.com/UncleGene/flay-actionpack/blob/master/lib/flay_actionpack.rb#L15

This is because the function being called has been updated to use a different signature: https://github.com/rails/rails/blob/348e609da369c4a32cdcab51a78edcd0ad2942c1/actionview/lib/action_view/template/handlers/erb.rb#L57
