1.更换国内源
查看Ubuntu18版本和codename（一定要注意codename对应）
1 lsb_release -a
1 No LSB modules are available. 2 Distributor ID: Ubuntu 3 Description: Ubuntu 18.10 4 Release: 18.10 5 Codename: cosmic
先备份
cp /etc/apt/sources.list /etc/apt/sources.list.bak
1 vim /etc/apt/sources.list 2 5 deb https://mirrors.ustc.edu.cn/ubuntu/ cosmic main restricted universe multiverse 6 deb-src https://mirrors.ustc.edu.cn/ubuntu/ cosmic main restricted universe multiverse 7 deb https://mirrors.ustc.edu.cn/ubuntu/ cosmic-updates main restricted universe multiverse 8 deb-src https://mirrors.ustc.edu.cn/ubuntu/ cosmic-updates main restricted universe multiverse 9 deb https://mirrors.ustc.edu.cn/ubuntu/ cosmic-backports main restricted universe multiverse 10 deb-src https://mirrors.ustc.edu.cn/ubuntu/ cosmic-backports main restricted universe multiverse 11 deb https://mirrors.ustc.edu.cn/ubuntu/ cosmic-security main restricted universe multiverse 12 deb-src https://mirrors.ustc.edu.cn/ubuntu/ cosmic-security main restricted universe multiverse 13 deb https://mirrors.ustc.edu.cn/ubuntu/ cosmic-proposed main restricted universe multiverse 14 deb-src https://mirrors.ustc.edu.cn/ubuntu/ cosmic-proposed main restricted universe multiverse
更新
1 apt update 2 apt upgrade
结果显示很快的
2.更换豆瓣pip
创建文件夹
mkdir ~/.pip
cd ~/.pip/
编辑配置文件
1 vim pip.conf 2 [global] 3 index-url = http://pypi.douban.com/simple 4 [install] 5 trusted-host=pypi.douban.com
安装pip3
1 pip install python3-pip
安装django速度25MB/s
pip3 install django
也可以每次使用单独的pip源
1 pip install pygame -i http://pypi.douban.com/simple 2 pip install pygame -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
