It breaks because Python installation cannot find zlib.
The solution is easy - provide CFLAGS from the xcode sdk:
$ CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install 3.8.6

This issue was about to drive me friggin' crazy ... 🤦 Many thanks for posting this Jakub 😄
I tried with this solution but didn't work, but these one worked for python 3.5, 3.6 and 3.9

Jakub, could you point me in the right direction, please. I am facing the same issue. In fact, the exact same issue when trying to install Python but my version is 2.7.7.
I infer that you are entering this code in the zshell in the M1 MacBook Pro, right?
If not, where is it that I should enter this code? I am really new to this. If I need to learn something else like xcode please point me in the direction that I need to be heading. Thanks in advance!
Hi Joseph,
unfortunately I don't have M1 MacBook or python 2.7 - so I cannot say if this is the same problem.
I'm still stuck with the same problem(( M1 mac
This unlocked a full day of messing with my python environments thank you.
likewise! thank you Jakub
