ImportError: Couldn't import Django. PYTHONPATH

Question

There was an error account.User that has not been installed but I solved this problem. After that, another error says The SECRET_KEY setting must not be empty.

I don't know whether my method to solve this problem is correct or not, I applied some solutions with Google. But now, there is an error ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment? But I already installed django and virtualenv. I don't know how to do it.

Recent error:

Traceback (most recent call last):
  File "/Users/leejunseo/PycharmProjects/ITM coding/manage.py", line 10, in main
    from django.core.management import execute_from_command_line
  File "/Users/leejunseo/PycharmProjects/ITM coding/venv/lib/python3.9/site-packages/django/core/management/__init__.py", line 12, in <module>

    from .base import *
ModuleNotFoundError: No module named 'django.conf.base'

The above exception was the direct cause of the following exception:

Answer 1

Your traceback is telling you exactly what is wrong :

Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

So you should relaunch your IDE or activate your environnement, as Django cannot be launch

Answer 2

I am using a Mac OSX 10.13.6. I have Python 3.9 installed.

I activated my venv, then installed Django. When I use 'pip list' or 'pip3 list', it lists Django as one of the Python packages that are installed. In addition, I was able to create a project using "django-admin startproject . If Django was not installed or I was not using venv, then I could not execute the django-admin command.

Also, I checked the venv/lib/python3.9/site-packages and django and other Python packages are installed in that directory. AND I did 'export PYTHONPATH=/Library/Frameworks/Python.framework/Versions/3.9'.

So, it is somewhat confusing why python3 is not finding Django. Any suggestions?
