PYGOBJECT version mismatch

[espiriki]

Was following the README.md file and got this error when running the "build-gst-python.sh" script:

checking for GST... yes
checking for PYGOBJECT... configure: error: Package requirements (pygobject-3.0 >= 3.8) were not met:

No package 'pygobject-3.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables PYGOBJECT_CFLAGS
and PYGOBJECT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

make: *** No targets specified and no makefile found. Stop.
make: Nothing to be done for 'install'.

Any tips on how to fix this?
