I am trying to install python 3.8.5 using pyenv on my new MacBook Pro.
I was able to install pyenv successfully and confirmed it was working fine. It is quite weird as I was able to install python 3.9.2 successfully using pyenv on my MacOS.
The problem arises when I tried to install another python version such as 3.8.5.
I get the error messages as below.
~ » pyenv install 3.8.5

I tried to follow some ways to resolve the issue as described in
https://github.com/pyenv/pyenv/wiki/Common-build-problems (common build problem)
However, I get the same outcome each time I try to install python versions using pyenv.
I am new to MacOS, I would like to get some advice on this. Could anyone help on this?
Thank you very much!
the error you are facing may be caused by an older version of the xcode command line tool. Please try typing and running the following command.It may change something.
xcode-select --install
LDFLAGS="-L$(xcrun --show-sdk-path)/usr/lib" pyenv install 3.8.5
I hope it works for you.
