运行命令后结果提示生成配置文件 C:\Users\xxxx\AppData\Roaming\pip\pip.ini

方法二 编辑配置文件

win + r，在运行程序框中输入 %APPDATA%：

在打开目录下新建 pip 文件夹，打开后在新建配置文件 pip.ini

pip.ini 配置内容如下：

[global]

timeout = 6000

index-url = https://pypi.tuna.tsinghua.edu.cn/simple

trusted-host = pypi.tuna.tsinghua.edu.cn

Linux 系统

编辑配置文件

我在 Ubuntu 中查看 pip 帮助信息中没有 config 选项，所以只好修改配置文件了，内容与 Windows 中的配置文件一致。

如果没有就新建如下目录和文件：

~/.pip/pip.conf

测试镜像源

填好配置内容后即可测试镜像源，命令显示请求的镜像源为 https://pypi.tuna.tsinghua.edu.cn/：
