For development we use poetry to handle dependencies. If poetry is not installed on your system you can install poetry using this command:
curl -sSL https://install.python-poetry.org | python3 -
Once poetry is installed you can install the current project including all dependencies using the following command:
poetry install
poetry creates a virtual environment so that the current project is isolated from the rest of the system. To run a command in the poetry virtual environment you type poetry run {command}. So to run the bbq tool you can type:
poetry run bbq -h
This only works if you are in the current directory. If you want to run the code from a different directory you can first make sure that the current version is installed in the poetry environment by running poetry install and then using the which command to get the full path of the installed version:
poetry install
poetry run which bbq
That will return a full path to an executable that can be run from any directory.
If we want to use numpy in our program we can add it as a dependency using the command:
poetry add numpy
poetry will then find a version of numpy that fits with the requirements of other packages and install it.
