Checked other resources

  • This is a bug, not a usage question. For questions, please use the LangChain Forum (https://forum.langchain.com/).
  • I added a clear and detailed title that summarizes the issue.
  • I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example).
  • I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue.

Error Message and Stack Trace (if applicable)

ImportError while loading conftest '/build/source/libs/langgraph/tests/conftest.py'.
tests/conftest.py:11: in 
    from langgraph.cache.redis import RedisCache
E   ModuleNotFoundError: No module named 'langgraph.cache.redis'

Description

  • #5834 added a Redis cache (defined in libs/checkpoint/langgraph/cache/redis) and referenced from libs/langgraph/tests/conftest.py among other places.
  • When building langgraph @ 0.6.6 for nixpkgs it cannot find the redis cache code when initializing tests.
  • The missing code is nominally in langgraph-checkpoint which hasn't shipped an update lately.

System Info

Attempting to build langgraph @ 0.6.6 with langgraph-checkpoint @ 2.1.1. (latest, last released July 17)
