# NOTE: following steps does work on my macOS 10.15.4, pyenv 1.2.18 :(
# Error example:
# ERROR: invalid Python executable: /Users/weaming/.pyenv/versions/3.8.2/bin/python3.8
# The python-build could not find proper executable of Python after successful build. 

# Finally solution: download .pkg installer from https://www.python.org/downloads/release/python-382/
# it includes its own private version of Tcl/Tk 8.6. It does not use any system-supplied or third-party supplied versions of Tcl/Tk.
