为什么mypy在运行django-reset-framework的预提交时会抛出错误？

Question

我正在尝试自动化我的测试和代码静态分析。我的.pre-commit-config.yaml如下所示：

# .
# .
# .
- repo: https://github.com/pre-commit/mirrors-mypy
    rev: 'v0.910'
    hooks:
      - id: mypy
        args: [--no-strict-optional, --ignore-missing-imports]
        exclude: "[a-zA-Z]*/[a-zA-Z]*/(migrations)/(.)*"
        additional_dependencies: [
            'tokenize-rt,
            'djangorestframework-stubs',
            'django-stubs',
        ]

pyproject.toml为：

[tool.mypy]
python_version = "3.8"
plugins = ["mypy_django_plugin.main", "mypy_drf_plugin.main"]

[mypy.plugins.django-stubs]
django_settings_module = "api.shop.shop.settings"

当我运行pre-commit run --all-files时，我得到以下错误：

Error constructing plugin instance of NewSemanalDjangoPlugin

ModuleNotFoundError: No module named 'rest_framework'

但是我已经在我的环境中安装了djangoresetframework和djangorestframework-stubs。这里的问题是什么？

Answer 1

pre-commit在隔离环境中运行其工具，您可以控制依赖关系(正如您已经看到的，它似乎(!))从mirrors-mypy readme中声明的additional_dependencies

看起来mypy_django_plugin缺少依赖项--值得注意的是，它尝试导入django和rest-framework，因此您需要确保在additional_dependencies中包含这些依赖项

请注意，您不需要tokenize-rt --这只是自述文件中的一个示例，因此您可以删除它
