执行pre-commit时出现AttributeError: 'EntryPoints' object has no attribute 'get'

执行pre-commit install时触发AttributeError: 'EntryPoints' object has no attribute 'get'错误，错误由flake8引发。已尝试安装importlib_metadata==4.13.0但问题未解决。

解决方法 #

核心原因 #

pre-commit为每个钩子创建独立的隔离环境，全局安装的importlib_metadata不会被flake8的钩子环境复用，所以之前的操作无法生效。

具体步骤 #

1. 修改flake8的依赖配置
   在pre-commit配置文件中，给flake8的additional_dependencies添加指定版本的importlib_metadata，同时修正拼写错误：

   -   repo: https://github.com/PyCQA/flake8
       rev: 3.9.2
       hooks:
       -   id: flake8
           additional_dependencies: [flake8-typing-imports==1.10.0, importlib_metadata==4.13.0]
           exclude: ^site-packages/  # 修正拼写：site-pacakges → site-packages
   

2. 清理pre-commit缓存
   删除旧的钩子环境，确保新依赖被正确安装：

   pre-commit clean
   

3. 重新初始化并验证
   重新执行安装命令，然后测试问题是否解决：

   pre-commit install
   pre-commit run --all-files
