Hi everyone. I am working my way through the tutorial. Whenever I run
dagster dev -f
I get the following error message. At the same time, I am not able to navigate to I am currently on this page of the tutorial: Does anyone know what might be happening here?

Hi @daniel. Thanks for sending that across. To give an update, in case anyone else runs into the same issue as me, here’s how we managed to resolve it: My .py files are in a subfolder in my repo, so I needed to specify the relative path: e.g
dagster dev -f *dagster/*
Also, prefixing the command with sudo was needed (perhaps due to being on an M1 Mac?). The full command that worked for me is thus:
sudo dagster dev -f dagster*/*
