[SOLVED] pip install PyGObject==3.50.0 complaints of stale meson even though latest meson present

pip install PyGObject==3.50.0 complaints of stale meson even though latest meson present

Upgrading PyGobject using

pip install  PyGObject==3.50.0 --verbose

gives the error (see full error at the end)

meson-python: error: Could not find meson version 0.63.3 or newer, found 0.61.2.
            [end of output]

even though I have the latest meson

>>>pip list | grep -i -e 'meson' -e 'pygo'
meson                        1.6.1
meson-python                 0.17.1
PyGObject                    3.42.1
