"No libdef files found" when trying to install

See original GitHub issue

I’m trying to use Flow on my angular app, so flow-typed install angular@4.4.6 but it fails with

• rebasing flow-typed cache...
ERROR: Unable to rebase the local cache repo. Error rebasing the `master` branch of the following repo:

What am I doing wrong? I'm new to Flow, so I can misunderstand something: if so, sorry)

I solved this problem in the following way：

Delete all files in the .flow-typed folder;
Re-run flow-typed install

Then, I waited a few minutes for the execution to be successful.

I guess the cause of this problem is the bad network condition.

The /Users/kynan/.flow-typed/repo part looks pretty strange to me, what’s going on in your .flow-typed directory? What happens if you wipe that folder? Obviously not an actual solution, but I’m curious to see what’s going on…
