一、ubuntu安装pip
sudo apt-get install python3-pip
二、依赖包不存在
sudo apt-get -f install（sudo apt-get -f install --fix-missing） 安装mysql-community-server
上述操作需要替换成国内源
cd /etc/apt sudo
cp sources.list sources.list.bak
sudo gedit sources.list
sources.list 如下
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted universe multiverse
