## 解决方案

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

## 无效尝试

- **** — This clears the cache but does not fix the underlying disk or permission issue that caused corruption. (50% 失败率)
- **** — This is error-prone and may introduce further corruption if the file format is not understood. (80% 失败率)
