I have an install issue :sweat_smile: In :thread:

```(test-prefect) ellawherritt@MacBook-Pro prefect_workshop % python flowtest.py

ModuleNotFoundError: No module named '_ctypes'```

I have tried using a different python version and installing a few different packages

Looks like this is the cause - I’ve seen it on a few Python threads:
```I expect that the root cause is missing libffi(-dev[el]) on your system, preventing _ctypes from building, so your quick fix would be to install that and try again.```

A different Python version might also work: <https://github.com/pypa/pipenv/issues/4901>

Several options here: <https://stackoverflow.com/questions/63996623/no-module-named-ctypes>

I was on 3.7 awhile ago but had to switch to 3.11 to resolve this error. Had no issue with it until today :melting_face:

Rejoice! I got it to work with 3.10. I'll take that as a win :slightly_smiling_face: Thanks!
