I've reproduced the environment you describe but do not get the error you are getting. Can you do a pip3 list and share it?

^^ Here you go good sir.

How did you solve?

[PcSpecific]

Same here. Is there any solution to this?

[jrupert-unity]

What versions of attrs and cattrs do you have?

[lrfreeman]

I fixed by moving from installing on linux using WSL, to using windows for the install
