Root Cause

The pytest cache directory is corrupted, often due to a previous test run being interrupted or disk issues.

generic

中文

pytest 缓存目录损坏，通常是由于之前的测试运行被中断或磁盘问题。

Workarounds

  1. 95% success 
    Delete the .pytest_cache directory manually: `rm -rf .pytest_cache`
  2. 90% success 
    Run pytest with --cache-clear and ensure proper disk space and permissions.

Dead Ends

Common approaches that don't work:

  1. 50% fail

    This clears the cache but does not fix the underlying disk or permission issue that caused corruption.

  2. 80% fail

    This is error-prone and may introduce further corruption if the file format is not understood.
