Python 在不同的机器上用mypy扫描包会产生不同的结果

我试图使用vim中的ALE插件和命令行上的

mypy

键入check并获得不一致的结果

更新：在下面@aaron的评论之后，我在另一台机器上签出了代码，它按预期工作：我在那里得到的错误比在我的主开发机器上更多。所以vim内部的ALE给我的结果与另一台机器上的过程相同。我不明白为什么

两者都应该给我相同的结果，但我注意到ALE给我的结果比命令行多。我想知道调用

mypy

的CLI有什么不对

设置和环境以重现我所经历的行为（不需要ALE）：

• 克隆上面链接的存储库并签出修订版

  4fb26c4e5b

• 运行

  python3-m-venv-env

• 运行

  /env/bin/pip安装-e.

• 运行

  /env/bin/pip安装mypy

现在，使用此环境，键入检查目录

puresnmp

将产生以下结果：

$ ./env/bin/mypy puresnmp
puresnmp/aio/api/raw.py:505: error: Type signature has too few arguments
puresnmp/api/pythonic.py:239: error: Type signature has too few arguments
puresnmp/api/raw.py:490: error: Type signature has too few arguments
puresnmp/test/asyncmock.py:18: error: 'yield' in async function
Found 4 errors in 4 files (checked 38 source files)

使用

/env/bin/mypy puresnmp/***.py

或

/env/bin/mypy-p puresnmp

生成与上述相同的报告

但是，当显式指定文件时，我会得到更多的错误（恰好与ALE错误相对应）：
