Tips: When you encountered an unknown error can not install the package, you can go back to consider the following recommendations:
to find ways to update the version of Python! ! !
If you can not update the version of Python,
think of ways to pip updated version! ! !
Recommended reason: 1) installed on the need to develop a networked machine can pack 2) package installed packages 3) offline installation package packaged
