rake eslint:run_all or rake eslint:run[filename] not working

[ganeshkumar]

Please note that i am using node version 0.12.4

filename: is the exact file path of js file.

when i run rake eslint:run_all/ rake eslint:run[filename] below error is throwing up

ExecJS::ProgramError: TypeError: Cannot read property 'firebug' of undefined Function.useColors (eval at <anonymous> ((execjs):1:266), <anonymous>:13435:75) createDebug (eval at <anonymous> ((execjs):1:266), <anonymous>:13688:29) Object.debug (eval at <anonymous> ((execjs):1:266), <anonymous>:49889:29) s (eval at <anonymous> ((execjs):1:266), <anonymous>:12502:620) eval (eval at <anonymous> ((execjs):1:266), <anonymous>:12502:671) Object../debug-helpers (eval at <anonymous> ((execjs):1:266), <anonymous>:47845:13) s (eval at <anonymous> ((execjs):1:266), <anonymous>:12502:620) eval (eval at <anonymous> ((execjs):1:266), <anonymous>:12502:671) Object../code-path-segment (eval at <anonymous> ((execjs):1:266), <anonymous>:48117:23) s (eval at <anonymous> ((execjs):1:266), <anonymous>:12502:620) Tasks: TOP => eslint:run_all

Please let me know anything is wrong? trying with latest version 1.3.0 and 1.2.2 getting same error.

but 1.2.1 works only for js files not es6 files.

OK, found where and how to fix this one...

First thought of mine was to pass another runtime to ExecJS...

EXECJS_RUNTIME='Node' rake eslint:run_all

Which didn't work since the runtime is hard coded...

eslint-rails/lib/tasks/eslint.rake

Line 1 in 97c5b53

ENV['EXECJS_RUNTIME'] = 'RubyRacer'

So, the solution is to add gem "therubyracer" to your Gemfile, run bundle install, and you're done.

What is weird is that therubyracer is a dev dependency and not a common dependency...

Maybe a pull request to fix that would be accepted?
