3 设置清华源

 临时使用

安装单个库时，通过 -i 参数指定清华源：

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

永久设置

方法 1：命令行设置

打开命令提示符（Windows）或终端（Mac/Linux），执行以下命令：

# 设置清华源为默认源
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

方法 2：手动创建配置文件

1. Windows 系统：

   • 在文件夹地址栏输入 %APPDATA% 并回车，进入应用数据目录
   • 新建 pip 文件夹，在其中创建 pip.ini 文件
   • 打开 pip.ini 并写入以下内容：

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