Ubuntu换国内源（清华）—系统、pip、conda

一、系统换源

1. 打开sources文件

sudo gedit /etc/apt/sources.list

2. 将下列清华源地址复制到改文件中，保存后退出

# 清华源
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

3. 更新源

sudo apt-get update

二、pip换源

2.1 pip临时换源

pip install ***（你要下载的包）   -i https://pypi.tuna.tsinghua.edu.cn/simple

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

2.2 pip永久换源

vim使用命令

i 插入模式
Esc 退出插入模式
：wq或者 ：wq! 保存并退出

cd ~                    				  # 进入家目录 
mkdir .pip         				          # 新建.pip隐藏文件夹
cd .pip                				      # 进入.pip文件夹
touch pip.conf    			   	          # 新建pip.conf文件
vim pip.conf           				      # 用vim编辑pip.conf文件 

添加内容：

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

2.3 pip其余国内源地址

https://pypi.douban.com/  ————    豆瓣 
 
https://mirrors.aliyun.com/pypi/simple/ ———— 阿里云
 
https://pypi.tuna.tsinghua.edu.cn/simple/ ————清华大学

https://pypi.hustunique.com/ ————华中理工大学 
 
https://pypi.mirrors.ustc.edu.cn/ ————中国科学技术大学 

三、conda换源
