Get matplotlib on top. Choose the correct package based on python version (2.x / 3.x) and bit (32/64).

 32-bit 2.7: matplotlib-1.5.2-cp27-cp27m-win32.whl 64-bit 2.7: matplotlib-1.5.2-cp27-cp27m-win_amd64.whl

Answer 2

I solved this by taking version 1.5.1

 pip install matplotlib==1.5.1 

It seems that the installer version 1.5.2 is not working.

Answer 3

As you can see, the png and freetype modules are missing. You need to install them separately.

Try the following:

 > pip install freetype-py > pip install pypng > pip install matplotlib 

Answer 4

I had the same problem.

It seems that my peak was v7, which is old. Updated to version v9 using the "Update" button. then tried to install matplotlib again and was successful this time.

maybe it helps

Answer 5

I ran into the same problem with you and here is my solution

This has a problem with python 3.6 integrated with the latest pip. so I installed python 3.5.2 using pip, but I am not updating pip. And you can install matplotlib this way.

I hope I can provide a possible solution
