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 [< file-option >] 参数，即为 --global 、–user 、–site，对应上面不同的目录。而–user是默认位置。
Usage: pip config [<file-option>] list pip config [<file-option>] [--editor <editor-path>] edit pip config [<file-option>] get name pip config [<file-option>] set name value pip config [<file-option>] unset name pip config [<file-option>] debugDescription: Manage local and global configuration. Subcommands: - list: List the active configuration (or from the file specified) - edit: Edit the configuration file in an editor - get: Get the value associated with name - set: Set the name=value - unset: Unset the value associated with name - debug: List the configuration files and values defined under them If none of --user, --global and --site are passed, a virtual environment configuration file is used if one is active and the file exists. Otherwise, all modifications happen on the to the user file by default.Config Options: --editor <editor> Editor to use to edit the file. Uses VISUAL or EDITOR environment variables if not provided. --global Use the system-wide configuration file only --user Use the user configuration file only --site Use the current environment configuration file onlyGeneral Options: -h, --help Show help. --isolated Run pip in an isolated mode, ignoring environment variables and user configuration. -v, --verbose Give more output. Option is additive, and can be used up to 3 times. -V, --version Show version and exit. -q, --quiet Give less output. Option is additive, and can be used up to 3 times (corresponding to WARNING, ERROR, and CRITICAL logging levels). --log <path> Path to a verbose appending log. --no-input Disable prompting for input. --proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port. --retries <retries> Maximum number of retries each connection should attempt (default 5 times). --timeout <sec> Set the socket timeout (default 15 seconds). --exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort. --trusted-host <hostname> Mark this host or host:port pair as trusted, even though it does not have valid or any HTTPS. --cert <path> Path to alternate CA bundle. --client-cert <path> Path to SSL client certificate, a single file containing the private key and the certificate in PEM format. --cache-dir <dir> Store the cache data in <dir>. --no-cache-dir Disable the cache. --disable-pip-version-check Don't periodically check PyPI to determine whether a new version of pip is available for download. Implied with --no-index. --no-color Suppress colored output --no-python-version-warning Silence deprecation warnings for upcoming unsupported Pythons. --use-feature <feature> Enable new functionality, that may be backward incompatible. --use-deprecated <feature> Enable deprecated functionality, that will be removed in the future.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
