Anyone ever ran into this before? Using pants 1.30.x we occasionally see

ERROR: No matching distribution found for <some dep>==x.x.x

That dependency clearly exists in pypi but it was updated in the last x minutes. It looks like pip is hanging on to its cache or not reaching out to pypi due to maybe the cache-control header being set too high. Anyone have a solution for this? We have tried clearing the pip cache, pants caches, or just waiting. sometimes it works… others it does not. What am I missing here?

Can you narrow down 1.30.x? 1.30.2 brought an upgrade to Pex 2.1.24 that includes new enough Pip that this should not be an issue.

1.30.0. I should bump this in our repo just havent had the time.

Ok. Great, yeah - using latest - 1.30.4 - is a good idea and should fix this for you.

updating now. will let you know how it goes

Any luck?

I will report back. Need the devs that were having the issues to play with it for a bit

Glad to hear it!
