Pip 安装在我自己的包中（在可编辑模式下）不会将该包暴露给我的系统

Question

问题描述

通过

coolcustom

安装我的

py -3.11 -m pip install -e .

软件包时，无法从其他地方导入该软件包。

重现我的问题的最小示例

我的项目结构如下

Documents/
├─ testing_package/
│  ├─ coolcustom/
│  │  ├─ __init__.py
│  │  ├─ setup.py
│  │  ├─ main.py

setup.py

看起来像这样

from setuptools import setup, find_packages

setup(
    name='coolcustom',
    version='0.1',
    packages=find_packages(),
)

使用安装包后

C:\...\Documents\testing_package\coolcustom>py -3.11 -m pip install -e .

Successfully built coolcustom
Installing collected packages: coolcustom

似乎没有弹出错误。我什至用

验证安装

py -3.11 -m pip list
Package                  Version      Editable project location
------------------------ ------------ ----------------------------------------------------
..other packages here
coolcustom               0.1          C:...\Documents\testing_package\coolcustom

但是，当我

cd

退出项目并尝试导入

coolcustom

包时，它失败了

cd ../..
C:...\Documents>py -3.11 -c "import coolcustom"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'coolcustom'

到目前为止我所尝试过的

1. 卸载可编辑版本后以不可编辑（正常）模式安装软件包，仍然不起作用
2. 我在

   \AppData\Roaming\Python\Python311\site-packages

   和

   \AppData\Local\Programs\Python\Python311\Lib\site-packages

中都找不到.egg-link文件
3. 但是我在

   coolcustom-0.1.dist-info

   中找到了

   __editable___coolcustom_0_1_finder.py

   文件夹、

   __editable__.coolcustom-0.1.pth

   和

   \AppData\Local\Programs\Python\Python311\Lib\site-packages

   ，这意味着设置确实做了一些事情。

我对使用setuptools非常陌生，所以也许我正在做的事情有一个明显的错误？

我忘记了 setup.py 应该位于外部文件夹中......抱歉
