1. 手动操作
1.1. 显示模块
1
|
pip list |
1.2. 显示过期模块
1
|
pip list - - outdated |
1.3. 安装模块
1
|
pip install xxx |
1.4. 升级模块
1
|
pip install - - upgrade xxx |
2. 自动操作
手动敲命令升级有点儿麻烦(特别是需要更新的模块比较多时),而我们完全可以用代码简单地实现全自动升级。
代码可以至GitHub下载,也可以复制本文中的代码:

Windows平台下可以运行下面的脚本,该脚本会自动获取管理员权限并进行更新(安装在C盘或者其他一些特殊的目录下可能需要管理员权限才能更新)。
