根因分析

测试文件使用了相对导入（例如 from . import module），但它不是包的一部分，或作为脚本运行。

English

A test file uses relative imports (e.g., from . import module) but is not part of a package, or is run as a script.

generic

解决方案

  1. 90% 成功率 
    From the project root, run: python -m pytest tests/
This ensures the current directory is in sys.path and relative imports work if tests are part of a package.
  2. 95% 成功率 
    pip install -e .
Then use absolute imports like 'from mypackage import module' in tests.

无效尝试

常见但无效的做法:

  1. 70% 失败

    If the test is run as a top-level script, relative imports still fail because there is no parent package.

  2. 60% 失败

    This may work but can break if the package structure changes or if the test is run from different directories.
