The first thing we’ll want to do is create a virtual environment. This will let us install modules that don’t mess with the rest of the system.

All of these commands should be run in the root folder of the application (the folder that src is inside of). Run the following command to create a folder (.venv) the virtual environment will be stored in.

python -m venv .venv

Next, we’ll want to activate the virtual environment. This needs to be done every time you run the application. If you’re using the bash shell the following command will active the virtual environment. (The bash shell is the default in Ubuntu. If you haven’t changed it this what you want)

source .venv/bin/activate

Now that we’ve created and activated a virtual environment, we can install the missing package.

The repository you linked has a requirements.txt file we can use to install all the required modules without typing them out by hand. This can be done using pip and the ”-r” flag.

pip install -r requirements.txt

Now that everything is installed, you should be able to run the application as normal with:

sudo python -m src

If you close your terminal window, you’ll have to reactivate the virtual environment the next time you want to run the script/program. You can also write a bash script to do this for you.

If you don’t want to setup a virtual environment, you can install the modules user wide. This will make it so the installed packages are available every time you run python. You can do this with pip as follows. Make sure to run this command in the root folder of the application (the folder src is in)

pip install -r requirements.txt

You should then be able to run the script/program as you did before with

sudo python -m src
