如何在python中自动安装缺少的模块？

Question

I want to release my simple python script which use some extended module such as argparse and watchdog . I don't think it reasonable to make the assumption that user of my script already has these modules installed. So I think I should include a configure script to test user environment (if I can automatically install these missing modules, that couldn't be better:P) in the release.

My question is: is there any utilities like configure for c program. If no such things, is it possible to adapt configure to python environment? Otherwise I have to compose some from scratch:(.

Thanks and best regards.

Answer 2

use PIP with a text file stating all required modules. like so:

pip install -r requirement.txt

You can also use pip to install the modules. PIP is replacement of easy_install .
