Greetings all,

Running Thonny v4.1.7 installed on a Windows 10 Pro machine.

Can anyone tell me why Thonny can't find PIL?

Here is Thonny next to a Command Prompt window:

Thank you.

How did you install PIL?

Are you running in a Virtual Environment?

Found the issue. Was running using the Thonny python versus running the locally installed version.

Changing the version solves the issue.

Just for clarification, it wasn't the version of Python that was the problem but the 'site-packages' that it was pointing to that prevented it from finding PIL.
