#19011 .gitignored named_caches_dir results in whacky behavior Issue created by cburroughs Describe the bug Under certain conditions setting

named_caches_dir

to a directory that is .gitignored results in python import errors and general whacky behavior. Using

named_caches_dir

within the git repo is sometimes used in CI, where GitLab for example is cranky about caching files outside of what the call the "build root". I've extracted a smallish if not minimal case at: https://github.com/cburroughs/example-python/tree/crazy-cache
