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

Mason Menges · Answer

Hey < Dan Horne> does this work without specifying the ` pre` flag i e `pip install prefect` to install the latest stable version of prefect

Zanie · Answer

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
