I\'m trying to install Pillow 3.1 on Windows. Per the instructions, I should be able to just type in:
pip install Pillow
But I get:
ValueEr
I spent almost a day figuring out what is wrong with pillow installation. It was working fine till yesterday and suddenly stopped working from today. Finally got it figured out, Few of my team mates upgraded python to 3.6 version which is now available for download. Since Pillow is not yet made compatible with 3.6 and is supporting only till 3.5.2 this error popped up.
Resolution is to check if Pillow supports your version of python. Once I reverted python back to 3.5.2 the installation worked like a charm and no errors encountered.
Hope this help resolve your issue.
