Hi all, while evaluating orchestration engines, I discovered prefect today. So I decided to give it a whirl, and the pip install failed on both Windows 10 and Mac OS 12.4.

Hi @Dan Horne Would you mind editing your message to cut and paste the output/code into the thread here? That will clean up the channel a bit. If you want, you can format it using ``` before and after your post to format as a "code block"

Hey @Dan Horne does this work without specifying the

--pre

flag, i.e.

pip install prefect

to install the latest stable version of prefect?

With

--pre

it’ll attempt to install pre-releases of prefect and all of prefects dependencies. It looks like one of our dependencies has an uninstallable prerelease.
