Steps to Reproduce

1. Use Python 3.8.13
2. pip install fidesctl

Expected behavior

Should be able to install

Environment

• Version: fidesctl 1.7.0
• OS: M1 mac Monterey
• Python Version: 3.8.13, but works with 3.9.11
• Pip Version: 22.0.4
• Docker Version: N/A

@allisonking I think this is an M1 issue, as I'm also using 3.8.13 on windows and its fine. What I'm assuming is happening here is that there isn't a wheel built for pycares for M1 yet

[allisonking]

yeah, @sanders41 figured out that the problem is I needed to pip install wheel first to get this to work 🤔

[ThomasLaPiana]

is that worth documenting or can we close the issue? not sure if this would be a common issue for users or a relatively rare occurrence

[sanders41]

@ThomasLaPiana i think your initial thought is correct. She needed wheel so pip could build a package that didn’t already have a version built for M1. What is weird is I could pip on my M1 without installing wheel first. I figure this has to mean I have a build tool installed that she doesn’t have, but we couldn’t figure out where our setup was different.

Since the issue is specific to M1 Macs running Python < 3.9 I think it will be a rare occurrence.

interesting, good to know!
