greenkeeper-lockfile-update errors with missing directory in node_modules

[wolfy1339]

$ node --version
v10.8.0
$ npm --version
6.2.0
$ nvm --version
0.33.11

Running on TravisCI using stable nodejs release. greenkeeper-lockfile-update (using v2, and set the GK_LOCK_DEFAULT_BRANCH="v4" env variable) reports that the branch is not a greenkeeper branch, but it is reporting it wrong, since Greenkeeper was opening PRs just fine before this on that branch. I just added a package-lock.json to my repo

[travi]

have you checked both builds for the PR? one is identified as master because it merges with master. the other is the only one that will be detected as the greenkeeper branch.

[wolfy1339]

Okay, so that was that. Now it is still not working. Here's the output: https://travis-ci.org/wolfy1339/m8tro-bootstrap/builds/414477822#L549

That’s a really weird one, it looks like package.json and node_modules/ don’t agree with each other.

I have tried deleting the cache, nothing works. This has happened on a greenkeeper PR now. It is the same error as before

I have the same error with node 8.

$ node --version
v8.11.4
$ npm --version
5.6.0
$ nvm --version
0.33.11
$ greenkeeper-lockfile --version
2.4.0

Here's the output: https://travis-ci.org/NationalBankBelgium/stark/jobs/422057979

And here you can find the error:

Would you have any idea how to solve this ? 😊

Thanks for the help

@janl @travi Is there anything we could do to help you guys out move this along?

[travi]

sorry @wolfy1339, i'm not actually part of the greenkeeper team. i only mentioned what i did above to attempt to help clarify what seems to be a common confusion point with travis (note that multiple branch confusion is not a problem with greenkeeper).

Quick heads-up for those who only have public dependencies, you can now stop using greenkeeper-lockfile: https://blog.greenkeeper.io/announcing-native-lockfile-support-85381a37a0d0

We’ve put all our energy behind that, and now we have time to look into this issue again. Thanks for all your patience!

https://github.com/greenkeeperio/greenkeeper-lockfile/releases/tag/v2.7.1 should stop failing the build, and print the path that seems to go away for no reason :)
