Python setuptools / distutils用Makefile为`extra`包定制构建吗？
Python setuptools / distutils用Makefile为`extra`包定制构建吗？
提问于 2018-03-15 11:31:57
安装程序： 现在，对于其中一个额外（我们称之为extra1），我需要调用一个非python库的二进制文件X。
问题1：如何make使用setuptools / distutils在包的构建过程中运行终端命令（即我的情况）？
问题2：如何确保只有extra1在安装过程中指定相应的终端命令时才执行这样的终端命令？
例：
- 如果有人跑步
pip install my_package，则不会发生这种附加的图库编辑X。 - 如果有人在运行
pip install my_package [extra1]，模块X需要编译，所以相应的二进制文件将被创建并在目标机器上可用。

这些文档在setup.py和pip之间的交互过程中非常稀少，但是你应该能够做到这样：
import subprocess
from setuptools import Command
from setuptools import setup
class CustomInstall(Command):
user_options = []
def initialize_options(self):
pass
def finalize_options(self):
pass
def run(self):
subprocess.call(
['touch',
'/home/{{YOUR_USERNAME}}/'
'and_thats_why_you_should_never_run_pip_as_sudo']
)
setup(
name='hack',
version='0.1',
cmdclass={'customcommand': CustomInstall}
)
该命令是在主要安装序列之后执行的，因此根据您尝试执行的操作，可能无法正常工作。请参阅详细的pip安装输出：
