Solve the problem.

Because Python's version is too low. Now with 3.6

saintkings-mac-mini:~ saintking$ which Python

/usr/bin/python

Mv/usr/bin/python/usr/bin/python_backup

mv /usr/local/bin/python /usr/local/bin/python_backup

>>> Import Matplotlib.pyplot as Plt

In many cases we want to ignore the past download of the installation package, the direct download installation can use –ignore-installed This parameter, such as I found the matplotlib Mplot3d part of a bit of a problem, I would like to re-download the installation again, can do so

This will download the relevant packages (NumPy, Pytz, six, Python-dateutil, Cycler, pyparsing, matplotlib) and install them all over again.

saintkings-mac-mini:~ saintking$ sudo pip install--upgrade--ignore-installed matplotlib
