win10下，pip安装的时候权限不够，无法安装；
1.以管理员权限权限运行cmd;
2.使用 --user 参数；不过只能当前安装的人使用；安装路径也在%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以管理员权限运行代码；
