Found pyenv, but it is badly configured ($reason). pyenv might not
work correctly for non-interactive shells (for example, when run from a script).
${(%):-"%B%F{yellow}"}
To fix this message, add these lines to the '.profile' and '.zprofile' files
in your home directory:
${(%):-"%f"}
export PYENV_ROOT="$pyenv_root"
export PATH="\$PYENV_ROOT/bin:\$PATH"
eval "\$(pyenv init --path)"
${(%):-"%F{yellow}"}
You'll need to restart your user session for the changes to take effect.${(%):-%b%f}
