二、更换镜像

# 查看配置
python -m pip config list

# 更换为阿里源
python -m pip config set global.index-url https://mirrors.aliyun.com/pypi/simple

# 更换为清华源
python -m pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

或按如下操作：建个文件 ~/.pip/pip.conf, 内容如下：

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

或

[global]
timeout = 6000
index-url = http://e.pypi.python.org/simple
[install]
use-mirrors = true
mirrors = http://e.pypi.python.org

或

[global]
index-url = http://b.pypi.python.org/simple
[install]
use-mirrors = true
mirrors = http://b.pypi.python.org
