@amitcross could you explain if you solved this issue and how?

[amitcross]

No that issue is not solved while installing from PIP but as a temporary solution I pasted entire Library to my Python folder

[amitcross]

freetype: no [The C/C++ header for freetype (ft2build.h)
could not be found. You may need to install the
development package.]
png: no [The C/C++ header for png (png.h) could not be
found. You may need to install the development
package.]

I also have this problem.

[Locvic]

This is still a problem, haven't found a fix yet...

[aidanchandra]

Why was this closed? There's clearly no fix yet.

I updated the requirements to
cycler==0.10 numpy==1.15.0 matplotlib==3.3.4

and ran the example and it works.

I am using python Python 3.7.6

I am not opening a PR as the project doesn't have any test and I haven't tested all features.

Check if it works in your case

Just tried with Python 3.8.3 but it doesn't seem to work.
EDIT:

RuntimeWarning: Pillow does not yet support Python 3.8 and does not yet provide prebuilt Windows binaries. We do not recommend building from source on Windows.

It seems like Python3.8+ is not supported by Pillow yet. This should work on anything below, 3.8
