Hi! This sounds like it might be a duplicate of #4706, which was fixed in #4730 (on master only so far, so not in yarn 1.2.1).

Could you try with yarn master and see if that helps? You'll need to clone the yarn repo, build it and call the generated script instead of the existing yarn install - see:
https://github.com/yarnpkg/yarn/blob/master/CONTRIBUTING.md

If that doesn't help, could you provide a testcase repository with steps to reproduce? :-)

@edmorley is it going to be in a nightly build in some time? I have a nightly build installed, easier than clone & build master

[edmorley]

Ah yes it's probably easier to try the Nightly build (the fix should be in there, since it landed 7 days ago). See:
