配置中的 mypy_path 没有被拾取

问题描述 投票：0回答：2

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

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，以下命令：

mypy -m mypy_minrepro.test.main

我得到：

所以没有找到stubs目录。现在我不想真正移动这些目录，那么我该如何修复这个结构呢？

好的，我已经理解了 mypy_path 语义。 2个问题：

首先，除非使用 

--config-file
传递，否则 mypy 将在调用命令的当前工作目录（然后在其他全局位置）中查找 mypy.ini 。 来自文档（强调我自己的）：

默认设置从 mypy.ini、.mypy.ini、pyproject.toml 读取， 或 setup.cfg

在当前目录。设置覆盖 mypy 的 内置默认值和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

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
），那么它是相对于运行 mypy 命令的当前目录。因此，即使 mypy 找到我的配置文件（通过手动传递它），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。

要解决此问题，请使用

$MYPY_CONFIG_FILE_DIR/stubs

 定义相对于配置文件（无论其位于何处）的路径。

对于那些来到这里寻找答案的人来说，这是另一个花絮/可能性。格里多的自我回答给了我所需的线索。

我正在使用 PyCharm、VSCode 和 lintrunner 来运行 MyPy（不要问！）。

    PyCharm
来自 Roberto Leinardi 的功能更强大的 PyCharm MyPy 插件允许您在单个文件或模块上运行 MyPy。不幸的是，我们根本不清楚它是从定义源文件或模块的目录运行它，而不是从项目目录或 MyPy

.ini

 文件的位置运行它。这意味着 ini 文件中的文件名被解析，嗯，不是按照您希望的方式。 :-) 我正在使用共享的
.mypy.ini
，因此我在
mypy_path
 中的文件名前面加上了
"$MYPY_CONFIG_FILE_DIR"
，以防我的同事的路径中有空格。

    Visual Studio Code（又名 VSCode）
不幸的是，引号破坏了来自 Matan Gover 的 VSCode 功能更强大的 mypy 插件。

叹气。
