First of all, at first I according to the textbook way of operation, has been shows PIP did not attribute the main, after trying a number of other methods also is so, at first I was using a python's built-in PIP, version is 9. A few, I just want to be version of the problem, so I just open a command window, activate the environment (because I was the third project comes first, so I opened the third project directory first, then activate it environment), then use PIP list view installed which packages, then role python -m PIP install - upgrade PIP 19.3.1 version of it to upgrade to the latest,

Then, you will see your second project on which position, the command to switch to change directory, the environment or activated, then use PIP install matplotlib command can be installed directly, and it is automatically match your system and python version, and download the needs of other packages,

Outside input python, bring up the simulation window, enter the import matplotlib after press the return key, no errors, that installation is successful, you can press CTRL z exit the simulation window, and then enter the PIP list you can see the matplotlib and other just download package together,
