win10下，pip安裝的時候權限不夠，無法安裝；
1.以管理員權限權限運行cmd;
2.使用 --user 參數；不過只能當前安裝的人使用；安裝路徑也在%APPDATA%；
--user Install to the Python user install directory for your platform. Typically ~/.local/, or %APPDATA%\Python on Windows. (See the Python documentation for site.USER_BASE for full details.)
3.用python以管理員權限運行代碼；
