PyPi——批量更新
pip --upgrade批量更新过期的python库
今天看了下系统环境,不少python库都有了更新,再用旧版本库可能已经不适合了,就想把所有的库都更新到最新版本。
查看系统里过期的python库,可以用pip命令
pip list #列出所有安装的库
pip list --outdated #列出所有过期的库
对于列出的过期库,pip也提供了更新的命令
pip install --upgrade 库名
演示:
root@CoralOptimal-VM:/usr/local/bin# pip list --outdated
Package Version Latest Type
--------- ------- ------ -----
pygobject 3.20.0 3.32.1 sdist
wheel 0.29.0 0.33.4 wheel
root@CoralOptimal-VM:/usr/local/bin# pip install --upgrade wheel
