Python-什么是setup.py？（python中的setup）

谁能解释一下，setup.py它是什么以及如何配置或使用？

答案1

setup.py是python文件，通常会告诉你要安装的模块/软件包已与Distutils打包并分发，Distutils是分发Python模块的标准。

这使你可以轻松安装Python软件包。通常写就足够了：

$ pip install . 

pip将使用setup.py安装模块。避免setup.py直接致电。

ERROR: Command "python setup.py egg_info" python-nss

[root@localhost ~]# pip install python-nss

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won''t be maintained after that date. A future version of pip will drop support for Python 2.7.

进入python-nss官网，写着To build python-nss you the C language header files and libraries for both NSPR and NSS will need to be installed. This is system and distribution specific, as such we cannot give you explicit instructions. On Linux typically these packages are called:

• nss-devel
• nspr-devel

yum install nss-devel -y

yum install nspr-devel -y

pip 无法导入 Cython 但 python setup.py install 可以

import os
from distutils.command.build_ext import build_ext
from typing import Callable

from setuptools import setup,Extension

from Cython.Build import cythonize
