Cannot pip install Pillow 7 on Python 3.9

Question

I'm facing an issue that I can't find a solution for it. I have Python 3.9.0a1 and pip 20.0.2 and I can't install different packages like Pillow while with other packages I don't have this issue, someone can help me to manage this error? Is it an issue related to the version of Python?

Error:

Answer 1

I had the same issue. This can be solved by cloning gym from github. I used GIT CMD app for cloning

    git clone https://github.com/openai/gym.git

    cd gym

    pip install -e .

[ In My windows 10 laptop

Python 3.9.5 (tags/v3.9.5:0a7dcbd, May 3 2021, 17:27:52) [MSC v.1928 64 bit (AMD64)] on win32

Answer 2

As @Njord mentioned, PIL is not maintained. Its fork, Pillow, is. Here's information about the project. The fork is not yet updated for Python 3.9 - as many packages will not be. You'll need to use Python 3.8 in the meantime until the update comes.

Pillow will get Python 3.9 support in its 8.0.0 release. As of today, it's scheduled for October 15, 2020.

Answer 3

The reason this is happening is because PIL hasn't updated to Python 3.9 yet, I am not aware of any fixes but right now it is best to downgrade to a Python version that can run PIL.

You aren't alone in this problem.
