在配置中卡在mypy_path中而不被拾取

Question

我有这样的结构：

mypy_minrepro
|   mypy.ini
|   __init__.py
|   
+---test
|   |   main.py
|   |   __init__.py
|   |   
|   \---stubs
|       \---untyped
|               main.pyi
|               __init__.pyi
|               
\---untyped
        main.py
        __init__.py

有一些简单的文件：

mypy.ini

[mypy]
mypy_path = test/stubs

untyped/main.py

def foo(x):
    return x ** 2

test/stubs/untyped/main.pyi

def foo(x: float) -> float: ...

test/main.py

from untyped.main import foo

if __name__ == "__main__":
    foo("invalid") # I want mypy to spot this error using my .pyi file

当我从包外部运行时，所以./mypy_minrepro，下面的命令如下：

mypy -m mypy_minrepro.test.main

我得到：

mypy_minrepro\test\main.py:8:错误:找不到名为"untyped.main“的模块的实现或库存根

因此找不到存根目录。现在我不想真的移动这些目录，那么我如何修复这个结构呢？

Answer 1

好的，我理解了mypy_path的语义。2问题：

首先，除非与--config-file一起传递，否则mypy将在调用命令的当前工作目录中查找mypy.ini (然后在其他全局位置)。从医生那里 (强调我自己的)：

默认情况下，从当前目录mypy.ini中的.mypy.ini、pyproject.toml或setup.cfg 读取设置。设置覆盖mypy的内置默认值，命令行标志可以覆盖设置。

这就是为什么在详细日志(-v)中我得到的是Config File: Default而不是Config File: mypy.ini。

第二个问题:如果mypy_path是相对的(例如mypy_path = test/stubs)，那么它相对于运行mypy命令的当前目录。因此，即使mypy找到了我的配置文件(通过手动传递)，如果我从父目录或子目录运行它，解析的mypy_path也会有所不同。

要解决这个问题，请使用$MYPY_CONFIG_FILE_DIR/stubs定义一个相对于配置文件的路径，无论它在哪里。
