When building environments where are the package hashes stored locally? I can't figure out where to clear whatever cache it's using.

Pretty-printed STDERR:
ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.

the packages are in s3. you may want to check your local .metaflow folder for local metadata cache

this is not an error from the nflx-extensions. This looks like a pip error directly.

We are working in building some rust libraries and then installing them. At the moment we are iterating and often create a new wheel with the same version number. However it has a different hash, and I can't figure out where pip is storing the cache because it says cache is disabled.

but are you installing it with the @conda or just manually?

It's definely a pip thing, I can recreate it outside of metaflow. pip is somehow storing the hash of the package somewhere and using it when doing a new install. Even if I uninstall the package and reinstall it has a hash mismatch.
