Ruby master/head - racc is now a bundled gem, not a default gem

When using bundler, breaks running RuboCop with Ruby master/head.

Line 12 in 0e0dfb8

require 'racc/parser'

Thanks for reporting. It's an external dependency, if #928 doesn't fix it we'll have to report it in the Racc repository.

I've published parser 3.2.2.2 with the latest Racc, could you test it please?

Thanks for the quick release. It didn't work. The problem is that Bundler will use 'default' gems, but will not use 'bundled' gems.

So, it's not a ruby/racc issue, as it's due to a change in ruby/ruby. Was debating whether to open an issue there...

JFYI, my normal Ruby for OSS work (Ubuntu & Windows) is master, so I noticed it this morning.

Sorry, I don't get how it affects RuboCop. Parser itself works well with the latest ruby-head, there are no errors on loading racc/parser. If our test suite is able to do require 'parser' then how's it different from RuboCop doing the same?

[MSP-Greg]

It's only when used with Bundler. Here racc is a development dependency. I think if it was made a 'normal' dependency things would be fine, but that's kind of a pita for me to test...

With it only as a development dependency, if I run bundle exec rake rubocop, it generates

LoadError: cannot load such file -- racc/parser

I opened #929 to resolve this issue and confirm a successful CI at rubocop/rubocop#11942 with Parser 3.2.2.3.
