为什么 ModuleNotFoundError: 没有名为“XXX”的模块，其中 XXX 是它自己

编程问答 2022-05-21

问题描述

我创建了一个 python 包并将其托管在我自己的 GitHub 存储库中。当我从 GitHub pip install 时，收到以下错误：

Getting requirements to build wheel ... error
...
ModuleNotFoundError: No module named 'XXX'

其中 XXX 是我尝试安装的软件包的名称。这对我来说没有意义。有人可以对此有所了解吗？

编辑 1： 我设法找到了一个表现出这种行为的永久存储库。请尝试以下操作：

pip install https://github.com/rm-hull/luma.core/archive/master.zip
pip install https://github.com/rm-hull/luma.oled/archive/master.zip

为了复制错误，您必须按照上面显示的顺序执行 pip 命令（如果您先执行第二个 pip 命令，则不会产生错误）。最后一个 pip 产生了以下错误：

...
ModuleNotFoundError: No module named 'luma.oled'

我在 Win10 上使用 Python 3.7.9、pip 21.0.1、setuptools 54.1.1。

注意：在 ... 的位置有一长串错误消息。

编辑 2： 这是安装 luma.oled 时的完整错误：

由 config.py 的 setuptools 触发的两个错误。但是如果在 Raspbian GNU/Linux 10 (buster) 下安装，则不会出现错误。

解决方法

需要更多详细信息才能准确回答，但您是否有机会在 setup.py 中从您自己的模块中导入某些内容？由于这是安装过程，因此无法访问它尝试安装的代码
