Error starting dev stack on Mac OS

Following the readme in https://github.com/edx/devstack,

After executing the command “make dev.provision”, I hit the error:

Starting edx.devstack.studio … done
++ docker-compose exec -T lms bash -c ‘source /edx/app/edxapp/edxapp_env && cd /edx/app/edxapp/edx-platform && NO_PYTHON_UNINSTALL=1 paver install_prereqs’
Build failed: Unknown task: install_prereqs
make: *** [dev.provision] Error 1

May I know if it’s something wrong with paver task? Thank you.
