This looks like you do not have meson correctly installed somehow, or
perhaps an unsupported version?
Looking at the location in ~/.local/bin/meson - I assume you have
installed it with pip.
Perhaps try the following:
pip3 install meson --upgrade
Or if you are running python2:
pip install meson --upgrade
Otherwise I would suggest you remove the build directory and try a clean
build from scratch as the simplest next step.
