python - Windows python setup.py install 不分发模块 python 文件

Question

我已经在网上搜索了几个小时，但我无法找出我做错了什么。我通过 python setup.py install 安装我自己的包。这是可行的，尽管我无法在系统上的任何地方导入 mymodule。

目录如下所示:

C:\PyDev\simple_test\mymodule
C:\PyDev\simple_test\setup.py
C:\PyDev\simple_test\mymodule\__init__.py

带有:__init__.py

def sayhello():
    print("Hello")

设置.py

from setuptools import setup
setup(
    name='mymodule'
)

命令行:python setup.py安装

这样做不会引发任何错误。但是当我查看站点包中安装的.egg文件时，它只包含一个EGG-INFO目录，并且没有任何源文件......

这是安装命令的输出:

(venv) C:\PyDev\simple_test>python setup.py install

如果我运行python setup.pydevelop它似乎确实有效。然后我就可以在整个系统中访问该包。

我不太确定原因是什么，但有两件事很突出:

• 您没有在 setup.py 中指定packages
• 模块目录的名称与主目录的名称不同

我可以想象，这两个因素的结合会导致 setuptools 无法找到您的源代码。

您可以尝试重命名 src 目录或将 setup.py 更改为

from setuptools import setup, find_packages

setup(name='mymodule',
      packages=find_packages()
)
