fix env error while invoked by Sublime Text 3's plugin "Better Coffeescript"

[trevorwang]

Invoked by Sublime Text 3, the following code will return as value of undefined

envs = process.env.HOME or process.env.HOMEPATH or process.env.USERPROFILE

It will cause path's error as following:

While I see where this does fix the error, I don't think it's the right solution. I recommend opening an issue in Better CoffeeScript instead to let them know that the environment needs to be passed.

I think it would be extremely frustrating to create a coffeelint.json in my home and then have it silently ignored.

I'm interested in following that issue, so please mention me and link back to here. coffeelint.org doesn't link to any sublime plugins because I haven't been able to find any that I've been able to make work. I normally use vim but tried sublime to just to try to find CoffeeLint plugins.
