Were you possibly using an older version of Dagster in your code and then installed a newer version in your local environment? Or changed your local environment so that it referenced a different version?

Either way, as a first approach to resolving it you could create a fresh virtual environment and install your Dagster project dependencies again. If your code is based from an older version of Dagster you should pin to that version in your setup.py/requirements.txt
