Prefect Community

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

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

I assume your run
```poetry add "prefect&gt;=2.0b"```
?

hmmm - if I use pip it works :disappointed:

yeah I often got problems when using poetry on an M1. Let me see if I can reproduce your error

Could be related to this maybe? <https://github.com/python-greenlet/greenlet/issues/181>

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

```poetry add "prefect&gt;=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?

Hey - have tried the above with no luck - will try to make a repro to see if its purely a me issue!
