调用`pip install`时运行自定义任务

Question

我想让我的python包"可以安装pip".问题是该软件包具有必须在用户的init shell脚本中提供的shell脚本(例如.bashrc).

但是在安装之后,用户并不完全知道脚本的去向(大概是/usr/bin,但我们无法保证).当然,用户可以运行which myscript.sh并手动编辑他的init脚本.

但我想自动完成这一步.我可以创建一个新的distutils命令,但pip install不会调用它.我可以扩展distutils.command.install.install,但安装通过pip中断(虽然通过工作python setup.py install):

setup.py

from distutils.command.install import install

class CustomInstall(install):
def run(self):
    install.run(self)
    # custom stuff here
    do_my_stuff()

setup(..., cmdclass={'install': CustomInstall})

通过安装包后运行自定义任务的最佳方法是什么pip？

你可以尝试from setuptools.command.install import install而不是使用distutils？
