如何让我的 python 程序在新计算机上自动安装模块？

Question

So I've written a program in python that I want to use on different computers, but to do this I need to install modules by opening up the command prompt and using "pip install ".

Is there a way to do this in the program without having to open the command prompt?

Answer 1

Yes, you can use the built-in pip module, which allows you to install python packages within your code.

eg

import pip
pip.main(["install", "pygame"])

in order to check for your package, you could use a try-except and check for an ImportError

Answer 2

I suspect if there is any way but here's the trick:

import os
os.system('pip install --user <module>')

And if you have many different packages to install, you may create requirements.txt file and just do pip install -r requirements.txt
