我使用pre-commit处理git项目的git钩子。当我使用它时，pre-commit run -a命令会不断跳过测试执行：
(smartexchange) trnbook:smartexchange ale$ pre-commit run unittest -a

直到我在代码中添加了requests和python-dotenv模块导入之前，git add . && pre-commit install && pre-commit run -a命令正常。这是我实际的.pre-commit-config.yaml文件。

什么可能导致这种行为？我该如何解决？
因为您使用的是language: python pre-commit，将创建一个隔离的环境来运行该钩子
例如，您可以使用additional_dependencies将事物添加到环境中：
- id: unittest
# ...
additional_dependencies: [dotenv]
或者，您可以使用language: system并要求用户设置必要的环境并激活它，而不是pre-commit自动执行]]
