一、pip换源命令

pip国内的一些镜像源：

• 阿里云 http://mirrors.aliyun.com/pypi/simple/
• 清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
• 中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/

1.临时使用：

pip的时候在后面加上-i参数，指定pip源

pip install SomePackage -i http://mirrors.aliyun.com/pypi/simple/

pip install SomePackage -i https://pypi.tuna.tsinghua.edu.cn/simple/ 

pip install SomePackage -i http://pypi.mirrors.ustc.edu.cn/simple/

2.永久修改

(1)Linux:

修改 ~/.pip/pip.conf (没有就创建一个)， 内容如下：

[global]
index-url = [国内镜像源链接]

如：

[global]
index-url = http://mirrors.aliyun.com/pypi/simple/

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple/ 

[global]
index-url = http://pypi.mirrors.ustc.edu.cn/simple/

(2)Windows

win+R 打开用户目录%HOMEPATH%，在此目录下创建 pip 文件夹，在 pip 目录下创建 pip.ini 文件, 内容如下

[global]
timeout = 6000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host = pypi.tuna.tsinghua.edu.cn

二、pip指令的使用

pip(Python Package Index)是一个以 Python 语言写成的软件包管理系統，使用 pip 可以非常方便的安装和管理 python 软件包。

执行 pip --help 命令，可以看到如下所示的帮助文档
