Space in dir path prevents webpack-dev-server from running about webpacker

[ytbryan]

So the fix is to escape the path at APP_PATH.

However, interestingly because Dir.chdir and File.foreach produce error when I pass in APP_PATH with space escaped. (is this a bug/flaw on ruby side?)

Therefore, I simply create a second APP_PATH called APP_PATH2 with the path escaped. Use it on the other paths that depends on it. Try it and let me know if this fix. It's working on my end.

And thank you for http://driftingruby.com/ :)

Or just use shellwords. Perhaps, needs a PR to fix this 👍
