I'm curretnly trying to use PIL with PyPy3, but no matter how I try to install it I get an error. First I tried to install it normally using pypy3 pip install pillow, but got the error that I need zlib. So after searching for a solution for a while I found the easy_install pillow command which fixed this problem for most people, but for me it leads to the same error. I hope somebody can help me out.

Error:

File "C:\Users\name\AppData\Local\Temp\easy_install-uqrsyszz\Pillow-4.0.0\setup.py", line 791, in  setuptools.sandbox.UnpickleableException: RequiredDependencyException('\n\nThe headers or library files could not be found for zlib,\na required dependency when compiling Pillow from source.\n\nPlease see the install instructions at:\n   http://pillow.readthedocs.io/en/latest/installation.html\n\n')
