Venv is Python's virtual environment. Python now mandates that packages either be installed globally by a package manager (not pip) or installed to a virtual environment with pip or some pip replacement. Venv is best suited for this use case, so to set up a virtual environment, you can use the following command.
python3 -m venv .venv
You can then activate the environment by running
source .venv/bin/activate
This is a bit different on Windows.

Once the venv is active, run
pip install -r requirements.txt
Then you may simply run the server:
python server.py
