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 unlocked a full day of messing with my python environments thank you.
likewise! thank you Jakub
I'm still stuck with the same problem(( M1 mac
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 tried with this solution but didn't work, but these one worked for python 3.5, 3.6 and 3.9

This issue was about to drive me friggin' crazy ... 🤦 Many thanks for posting this Jakub 😄
