pip.md

pip更新所有packages

cmd实现

pip list --outdated --format=legacy |awk '{print $1}' |xargs sudo -H pip install -U

这条应该是cmd的命令.

python实现

import pip
from subprocess import call
for package in pip.get_installed_distributions():
   call('pip install --upgrade' + package.project_name)

PowerShell

pip freeze > requirements.txt

再通过正则替换,将(==版本号)去掉.

==.*

最后

pip install -r requirements.txt --upgrade
