hi! trying out dagster and unable to install it properly - using an M2 Mac.

Installed dagster using instructions on the documentation

pip install dagster dagit --find-links=<https://github.com/dagster-io/build-grpcio/wiki/Wheels>

Have you tried creating a fresh conda environment and using only

conda install

(not

pip

) to install everything?

A fresh conda env worked for me when installing on my M2 recently, after receiving similar grpc related errors through pip. The only caveat was to install urllib3<2 first, as later versions are currently incompatible with Apple silicon.

works thanks
