ImportError: cannot import name 'livereload_port' from 'livereload'
You have both
django-livereload installed. Most likely, one was installed before the other,
and having both is an accident.
Assuming it's OK to just move to django-livereload, get rid of your code that imports or uses
pip uninstall -y livereload pip install django-livereload
Or equivalent with your preferred package manager. It's a simple issue really, but easy to miss.
(I initially assumed
livereload, but rather it's "inspired by"
and they have a namespace collision if you install both. Easy fix though.
