在调用`pip install`时运行自定义任务 [英] Run custom task when call `pip install`

问题描述

我想使我的python包"pip可安装".问题在于该程序包具有必须来自用户的初始Shell脚本中的Shell脚本(例如.bashrc).

I want to make my python package "pip installable". The problem is that the package has shell script that must be sourced in the user's init shell script (e.g. .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，但是我们不能保证).当然，用户可以运行which myscript.sh并手动编辑其初始化脚本.

But after the installation, the user don't exactly know where the script went (presumably /usr/bin, but we can't garantee). Of course the user can runs which myscript.sh and manually edits his init script.

但是我想使这一步骤自动化.我可以创建一个新的distutils命令，但pip install不会调用它.而且我可以扩展distutils.command.install.install，但是安装会通过pip中断(尽管可以通过python setup.py install进行操作):

But I want to automate this step. I can create a new distutils command, but pip install doesn't call it. And I can extend distutils.command.install.install, but the installation breaks via pip (although works via 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})

推荐答案

您可以尝试使用from setuptools.command.install import install而不是使用distutils吗?

Could you try with from setuptools.command.install import install instead of using distutils?
