永久性添加pip安装源

pip config set global.index-url --site https://pypi.tuna.tsinghua.edu.cn/simple

可得到如下结果：

可见，配置信息被写入pip.ini文件中，而此pip.ini被存放在python安装路径下。
打开该配置文件，可见：

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

显然，与配置参数中的 golbal.index-url 对应。(此处已经有一个之前设置的global）

查看pip文件的存储位置有

pip -v config list

可见：

即，除了“site”对应的目录，还有其他目录可能存放pip配置文件。

查看pip config 的配置方法

pip config -help

可见，下面的 [] 参数，即为 –global 、–user 、–site，对应上面不同的目录。而–user是默认位置。

删除配置信息

pip config --user unset site.index-urlpip config --user globalsite.index-url


把别处添加的源删除

查看pip下载的安装包的默认路径

python -m site

得见：

其中USER_BASE 和USER_SITE即为pip下载的安装包位置，此时目录还不存在。

查看如何修改安装位置

python -m site -help

得见：

所以，去 D:\Program Files\Python39\lib\site.py 修改配置信息，
将：

修改为自建目录：

其中
USER_SITE用于存放执行所下载的安装包所需要的脚本或程序
USER_BASE为安装包的下载位置
