PIP安装可编辑错误:模块未找到setuptools

Question

我有一个包，我已经在其他机器上安装了很多次，但在我的Mac上，我得到一个奇怪的错误。我试过在conda环境和虚拟环境中这样做，总是得到下面相同的错误。

注意:

• 我可以打开python shell并导入setuptools而不会出现问题。
• 没有-e
• 它列出了失败的命令，我可以手动运行。我已经通过pip升级了setuptools

Answer 1

我的问题在pyproject.toml。我没有意识到皮普正在看(虽然现在看起来很明显)。

问题是这样的，当我配置诗歌:

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

Answer 2

您的setup.py文件需要setuptools。一些Python包过去使用distutils进行分发，但现在大多数使用setuptools，这是一个更完整的包。这是一个关于它们之间区别的问题。

在Debian安装setuptools:

sudo apt-get install python3-setuptools

对于旧版本的Python (Python 2.x):

sudo apt-get install python-setuptools

然后检查你的虚拟环境。
