Module is suddenly not found, and can't install it either with pip

Question

Yesterday I was working on my project. Today, when I opened it, two modules aren't found. Yesterday they were, so that is pretty strange already. When I try to install using pip, it says 'Requirement already satisfied'. The modules I need to install are these:

from decouple import config
from celery.schedules import crontab

I already surfed around the internet trying random things, since I am new and learning django and python I find my problem very hard to understand.

EDIT: this might be helpful, but when I use pip, I get this error:

just@4G05D8DPAA4A78D hockeyvoorspeller % pip3 install decouple
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
    xyz, where xyz is the package you are trying to
    install.

If you wish to install a Python library that isn't in Homebrew,
use a virtual environment:

python3 -m venv path/to/venv
source path/to/venv/bin/activate
python3 -m pip install xyz

If you wish to install a Python application that isn't in Homebrew,
it may be easiest to use 'pipx install xyz', which will manage a
virtual environment for you. You can install pipx with

brew install pipx

You may restore the old behavior of pip by passing
the '--break-system-packages' flag to pip, or by adding
'break-system-packages = true' to your pip.conf file. The latter
will permanently disable this error.

If you disable this error, we STRONGLY recommend that you additionally
pass the '--user' flag to pip, or set 'user = true' in your pip.conf
file. Failure to do this can result in a broken Homebrew installation.

Read more about this behavior here: <https://peps.python.org/pep-0668/>

note: If you believe this is a mistake, please contact your 
Python installation or OS distribution provider. You can override 
this, at the risk of breaking your Python installation or OS, by 
passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

[notice] A new release of pip is available: 24.0 -> 24.2
[notice] To update, run: python3.12 -m pip install --upgrade pip

This might help solving the issue, thanks in advance

This question is similar to: What is a virtualenv, and why should I use one?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. — Anerdw

Can you share the screen shot of errror message, including IDE( like VS code, Intellij etc). — Vinay Vishwakarma

If you have created a virtual environment, activate it and try again, env\scripts\activate use this code

Yesterday I installed the packages without a venv. Today when I opened it the packages were gone so I made a venv. Installing in the venv goes fine, but in the python file it still doesnt find the packages

Do you get errors when the virtual environment is active?
