use child_process.spawn instead of child_process.exec to avoid maxBuffer exceeded

[wangsai]

exec's default maxBuffer is 200k, if the files in repository are huge, e.g. cdnjs, will cause the error Error: stdout maxBuffer exceeded.

Using spawn can avoid this error.

Could you send a PR?

Sorry, i'm not good at coffeescript.

js2coffee is your friend :)

I've run into this issue as well. A quick solution would be to make the 'maxBuffer' option configurable somehow:

+1, also suffering from this error.

@Dragony, making it configurable would not be a good solution. spawn is much more robust, in my opinion.

Have you implemented this in your fork @NecoleYu?
