Root Cause

The pytest cache directory is missing or corrupted, often due to manual deletion or concurrent test runs.

generic

中文

pytest 缓存目录丢失或损坏，通常是由于手动删除或并发测试运行。

Workarounds

  1. 95% success Clear the cache directory and let pytest recreate it. 
    rm -rf .pytest_cache; pytest --cache-clear
  2. 90% success Disable caching with --cache-clear flag each run. 
    pytest --cache-clear

Dead Ends

Common approaches that don't work:

  1. Creating an empty cache file manually 80% fail

    The cache file format is specific; an empty file may cause parsing errors.

  2. Ignoring the error and continuing 60% fail

    Pytest may fail to run or report incorrect results without cache.
