python 当pip安装需求文件失败时，就会发生愚蠢的事情

Posted 2021-05-09

# collects and installs each requirement fully one at a time.
# rather than collecting all packages then installing.

import pip
from subprocess import call

with open("requirements.txt", "r") as req:
    for package in req:
    call("pip install " + package, shell=True)
