根因分析

pytest 配置文件（pytest.ini、pyproject.toml 或 conftest.py）引用了当前 Python 环境中未安装的插件，导致 pytest 启动失败。

English

The pytest configuration (pytest.ini, pyproject.toml, or conftest.py) references a plugin that is not installed in the current Python environment, causing pytest to fail on startup.

generic

解决方案

  1. 95% 成功率 
    Install the missing plugin using pip: pip install pytest-cov, then re-run pytest.
  2. 90% 成功率 
    If the plugin is not needed, remove its reference from the configuration file (e.g., delete 'pytest-cov' from addopts or plugins list).

无效尝试

常见但无效的做法:

  1. 80% 失败

    Adding the plugin name to conftest.py's pytest_plugins list without installing it first still raises the same error.

  2. 50% 失败

    Ignoring the error and running tests with -p no:plugin may suppress the error but disables the plugin's functionality.
