ImportError: cannot import name 'hash_name' from 'fsspec.implementations.cached'

In get an ImportError on import pins in a new conda environment.

My environment.yml

name: pins_test
channels:
  - conda-forge
  - nodefaults
dependencies:
  - python=3.11
  - s3fs
  - boto3
  - pins
  - ipykernel

On import pins I get a

ImportError: cannot import name 'hash_name' from 'fsspec.implementations.cached' (c:\Users\Daniel\AppData\Local\mambaforge\envs\pins_test\Lib\site-packages\fsspec\implementations\cached.py)

hash_name is (supposed to be) imported here:

pins-python/pins/cache.py

Line 8 in ea242bc

from fsspec.implementations.cached import SimpleCacheFileSystem, hash_name

But fsspec/implementations/cached.py does not contain an importable hash_name function since this commit, AFAICT.

related to #212

It works now after rebuilding the environment, seems to have been a hickup in my conda env.

Thank you for bringing up this concern, @dpprdan!

You are correct, fsspec, an underlying dependencies in pins, changed how caching is handled very recently, so some versions are no longer compatible. You will run into this mismatch if you have pins<0.8.3 and fsspec>=2023.9.0. We plan to fix the fsspec import error soon. For now, if that error pops up again, try updating to the latest version of pins, which will restrict installation to only compatible versions.

I'm glad you were able to fix this in your own environment, and will close out this issue as solved. Let me know if you run into any other problems!
