當win10時，安裝pip 時，出現以下問題：
C:\Program Files\Python38\Scripts>easy_install.exe pip
error: can't create or remove files in install directory
The following error occurred while trying to add or remove files in the
installation directory:
[Errno 13] Permission denied: 'c:\\program files\\python38\\Lib\\site-packages\\test-easy-install-17916.write-test'
The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
c:\program files\python38\Lib\site-packages\
Perhaps your account does not have write access to this directory? If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account. If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.
For information on other options, you may wish to consult the
documentation at:
https://setuptools.readthedocs.io/en/latest/easy_install.html
Please make the appropriate changes for your system and try again.
我採用以下方式，看了一下，我把這個windows登錄用戶，增加了完全控制權限 ：
右擊：
最好把自己本電腦登錄的用戶，也需要打開：
當這個權限，打上後：就執行成功；
