Greenkeeper initial PR fails on npm install (npm ERR! code EINTEGRITY)

I’m not sure if this is an issue with greenkeeper.io or what but the initial pull request created by greenkeeper always fails on the npm install part.

npm ERR! code EINTEGRITY

Here’s the job that fails which is triggered by Greenkeeper’s PR.
Greenkeeper PR

And here’s the job of a normal PR: Build #125 - builds/448215024 (I can only post 1 link)

This GitHub Issues answer suggests there’s something wrong with your package-lock.json:

If this is happening on every PR created by Greenkeeper, I suspect the real issue lies with the tool.
