Feature Request

Running ./manage.py compress raises the error Invalid template name in 'extends' tag: ''

• [ ] How can I fix this error?

• [ ] Please consider a linter rule to catch this situation before I run ./manage.py compress

Hey @cclauss welcome back :) How would you suggest going about this? pick up the file name then verify the path is reachable from the template location?

Yes. That seems right to me.
