I noticed pyenv no longer works after upgrading to macOS 11.4. Immediately after the successful upgrade, I opened up iTerm and saw this message:

WARNING: pyenv init -no longer sets PATH. Runpyenv init to see the necessary changes to make to your configuration.

I then ran the pyenv init command and followed the instructions. I added the following commands in both ~./profile and ~./zprofile

export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"

Restarted my session by terminating iTerm2. The warning message is gone. But pyenv does not seem to switch to the version I set which is 3.9.5.

OS: macOS 11.4
Shell: zsh 5.8 (x86_64-apple-darwin20.1.0)
Pyenv version: 2.0 (updated on Monday via Homebrew)
