Pip Installation Doesn't Work (six, Numpy And Python-dateutil Requirements)

I'm a quite new to Python and want to install the Pillow package on Mac for Python 3.5. I use the pip install pillowcommand and get this error: Jaspers-MBP:~ jasperherrmann$ pip in

Solution 1:

Just do pip install --ignore-installed pillow, should solve your problem.

Solution 2:

For macOS, just try pip install --upgrade --user six. Good luck!
