Fails on yarn v1.0.x

[fulls1z3]

First of all, I'd like to thank everybody who contributed to this useful library, it saved a lot of time and effort to manage things while working on an enormous number of repositories with a tree-like dependency structure among each other.

And I'd like to point out that this greenkeeper-lockfile repository fails to return success code using yarn v1.0.x - as seen below:

failed

• https://circleci.com/gh/fulls1z3/ngx-config/70
  fixed
• https://circleci.com/gh/fulls1z3/ngx-config/71

In order to find this information, I had to play with some config/env values, and it's not fair to say the reason that the library fails 100% because of yarn v1.0.x - however, I think this information/observation would be useful to develop a fix.

If I can find some time, I'll try to make some contributions with a PR.

Cheers 👍

Is there a way to get the things that yarn is doing internally? The log isn‘t very helpful :)

It started failing on travis today as they are upgrading to yarn 1.3.x
