pip换源

更新pip版本到最新

python -m pip install --upgrade pip
sudo mkdir -p ~/.pip
sudo cp -v ~/.pip/pip.conf ~/.pip/pip.conf.bak

清华源

pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

pip 默认源的网络连接较差，临时使用该镜像站来升级 pip

python -m pip install -i https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple --upgrade pip

配置多个镜像源，源地址之间需要有空格

pip config set global.extra-index-url "<url1> <url2>..."

阿里源

pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/

腾讯源

pip config set global.index-url http://mirrors.cloud.tencent.com/pypi/simple

豆瓣源

pip config set global.index-url http://pypi.douban.com/simple/

换回默认源

pip config unset global.index-url

docker换源

sudo mkdir -p /etc/docker
sudo cp -v /etc/docker/daemon.json /etc/docker/daemon.json.bak

阿里源

sudo tee /etc/docker/daemon.json <<EOF
