根因分析

运行 pytest 时项目根目录不在 sys.path 上，导致 conftest.py 或测试模块中的导入失败。这通常发生在从子目录运行 pytest，或未以可编辑模式安装包时。

English

The project root is not on sys.path when pytest runs, so imports in conftest.py or test modules fail. This commonly happens when running pytest from a subdirectory or without installing the package in editable mode.

解决方案

  1. 95% 成功率 
    pip install -e .
# or with pyproject.toml:
pip install -e '.[test]'
  2. 90% 成功率 
    # pytest.ini or pyproject.toml
[tool.pytest.ini_options]
pythonpath = ['.']
# or CLI: pytest --import-mode=importlib

无效尝试

常见但无效的做法:

  1. 75% 失败

    Relative paths depend on CWD; running pytest from a different directory breaks it, and conftest.py is imported before test files so the fix is too late.

  2. 55% 失败

    Works for interactive runs but is not persisted for CI or IDE test runners, leading to flaky 'works on my machine' behavior.
