python -m site查看 pip 默认安装位置
PS C:\Users\Administrator> python -m site
sys.path = [
'C:\\Users\\Administrator',
'E:\\Program Files\\Python\\Python38\\python38.zip',
'E:\\Program Files\\Python\\Python38\\DLLs',
'E:\\Program Files\\Python\\Python38\\lib',
'E:\\Program Files\\Python\\Python38',

]
USER_BASE: 'C:\\Users\\Administrator\\AppData\\Roaming\\Python' (doesn't exist)
USER_SITE: 'C:\\Users\\Administrator\\AppData\\Roaming\\Python\\Python38\\site-packages' (doesn't exist)
ENABLE_USER_SITE: True
python -m site -help查看配置文件所在位置
PS C:\Users\Administrator> python -m site -help
E:\Program Files\Python\Python38\lib\site.py [--user-base] [--user-site]
Without arguments print some useful information
With arguments print the value of USER_BASE and/or USER_SITE separated
by ';'.
Exit codes with --user-base or --user-site:
0 - user site directory is enabled
1 - user site directory is disabled by user
2 - uses site directory is disabled by super user
or for security reasons
>2 - unknown error
打开配置文件，找到 USER_SITE = None，USER_BASE = None
# for distutils.commands.install
# These values are initialized by the getuserbase() and getusersitepackages()
# functions, through the main() function when Python starts.
USER_SITE = None
USER_BASE = None
自定义安装路径
# for distutils.commands.install
# These values are initialized by the getuserbase() and getusersitepackages()
# functions, through the main() function when Python starts.
USER_SITE = 'E:\\Program Files\\Python\\Python38\\lib\\site-packages'
USER_BASE = 'E:\\Program Files\\Python'
更换 pip 安装源
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip -U
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

可能是 Script 文件夹中没有 pip.exe，也可能是此路径没有添加到环境变量中，python -m ensurepip
PS C:\Users\Administrator> python -m ensurepip
