What version of pip are you using? With modern pip (9+), it should automatically pick the right version for you.

pip --version
pip install -U pip
pip install pillow

Pillow 7 dropped support for Python 2.7. If you would like to use Pillow 7, please switch to at least Python 3.5 - https://pillow.readthedocs.io/en/stable/installation.html. If you would like to continue to use Python 2.7, downgrade to Pillow 6.2.2.

Modern being the issue for me. I need to use Debian 8. Yes, after End-Of-Life. sigh

Good point about the pip version being maybe too old and not so smart. I have pip 8. I need to install something in a Python 2.7 environment that depends on Pillow 6, yet pip insists on using Pillow 7 and it fails. Luckily one can go through all errors and tell pip to install specific things by listing all packages with their desired versions (that still work with Python 2.7) in the same pip command, e.g.,

pip install numpy==1.7.1 scipy==0.18 pillow==6
