pip - Django: ERROR: Cannot install -r requirements.txt

Question

I was following the advices stated here How to run cloned Django project? because I have to work on a cloned Django project.

The steps I followed are:

1. Clone
2. Create and start a virtual environment
3. Install the project dependencies

And here is when I get the following error after running pip install -r requirements.txt :

ERROR: Cannot install -r requirements.txt (line 44) and websockets==7.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested websockets==7.0
    django-private-chat 0.3.0 depends on websockets==8.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Following the pip documentation https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies I installed websockets==8.1, but it didn’t fix the error.

What can I do? I don’t know how to "remove package versions to allow pip attempt to solve the dependency conflict". Am I forgetting any essential step while after cloning?

Thank you in advance.
