Support for Ruby 2.4.0

[danielbayerlein]

Support for Ruby 2.4.0 would be great. At the moment it crashed. I'm not sure if the problem is the gem "coffee-script" or "therubyrace".

Gemfile

gem 'coffee-script'

test.rb

require 'coffee_script'

CoffeeScript.compile File.read("script.coffee")

Output

therubyracer-0.12.2/lib/v8/conversion.rb

That sounds rather a lot like the problem is not in this gem.

This gem uses ExecJS to run the coffeescript compiler. Check that link for other runtimes you could use instead of therubyracer.

@matthewd Thank you for your feedback. You are right, therubyracer is currently not compatible with Ruby 2.4.0. rubyjs/therubyracer#430
