Python pip 安装与使用

pip 是 Python 包管理工具,该工具提供了对Python 包的查找、下载、安装、卸载的功能。

目前如果你在 python.org 下载最新版本的安装包,则是已经自带了该工具。

Python 2.7.9 + 或 Python 3.4+ 以上版本都自带 pip 工具。

pip 官网:https://pypi.org/project/pip/

你可以通过以下命令来判断是否已安装:

pip --version # Python2.x 版本命令 pip3 --version # Python3.x 版本命令

如果你还未安装,则可以使用以下方法来安装:

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py # 下载安装脚本 $ sudo python get-pip.py # 运行安装脚本
