No module named 'colorlog'

[ruslaniv]

I have installed colorlog as:
pipenv install colorlog --dev
Pipfile lists the following:

[dev-packages]
flake8 = "*"
mypy = "*"
colorlog = "*"

Then I import the package in the .py script
import colorlog
But when I run the script I get the error
ModuleNotFoundError: No module named 'colorlog'

I'm running python 3.8.1 on macOS 10.15.7

How can I troubleshoot the reason for this problem?

You are likely running your code with a different Python executable, or not using the virtualenv Pipenv manages (e.g. by using pipenv run script.py).

(Closing this as it's not a colorlog issue.)
