  ERROR: Failed building wheel for pycairo
Failed to build pycairo
ERROR: Could not build wheels for pycairo, which is required to install pyproject.toml-based projects

To resolve this on Ubuntu, install the pycairo library dependencies first as below:

$ sudo apt update
$ sudo apt install libcairo2-dev pkg-config python3-dev

To resolve this on MacOS, install the pycairo library dependencies first as below:

$ brew install cairo pkg-config

Once you have installed the dependencies, you are good to install roadmapper.
