Writes that Pillow is not installed, but is it?

Question

Python

Python 3.9
Django 2.2.7
Pillow 8.3.0

When starting the project, it says:

SystemCheckError: System check identified some issues:

ERRORS:

        HINT: Get Pillow at https://pypi.org/project/Pillow/ or run command "pip install Pillow".

I enter in the console "pip install Pillow":
