Pip 似乎没有在 setup.py 中安装模块

Question

我有一个setup.py文件，看起来像这样：

from setuptools import setup

setup(
  name='yeet',
  install_requires=[
    'cmake>=3.15.3',
    'Cython>=0.29.21',
    'glob2>=0.6',
    'hdbscan>=0.8.24',
  ],
)

当我使用 Python 3.7 conda 环境运行python setup.py install ，我得到：

Traceback (most recent call last):

ImportError: Cython not found! Please install cython and try again

有谁知道为什么没有安装 Cython，因为它在我的setup.py文件中？ 我知道我可以安装 Cython，但我想防止用户遇到这个障碍。 这里是hdbscan将 Cython 添加到其依赖项列表的解决方案吗？ 其他人可以提供的任何指示将不胜感激！

我认为你应该尝试这样的事情。

from setuptools import setup, Extension

setup(
    ...
    setup_requires=[
        'setuptools>= 50.3.0',
        'cython',

或类似的东西。

from setuptools import dist
dist.Distribution().fetch_build_eggs('Cython>=0.29.21')
