I thought I would have a play with 2.0 today - tried running the code here -> https://orion-docs.prefect.io/tutorials/first-steps/ - get following error?

Copy code

ValueError: the greenlet library is required to use this function. No module named 'greenlet'

Any ideas?

I was able to installed correct with poetry when running this command:

Copy code

poetry add "prefect>=2.0b"

I’m using an M1

Have you tried to create a new environment then install Prefect 2.0 with poetry to see if it works?
