pyenv-virtualenv: prompt changing will be removed from future release. configure `export PYENV_VIRTUALENV_DISABLE_PROMPT=1' to simulate the behavior.

I had that too and it is related to zsh's behaviour. You need to rehash after you activate a virtual environment in zsh. See pyenv/pyenv#31 (comment)

If you want to rehash automatically in zsh, either use zstyle ':completion:*' rehash true in your .zshrc (see ohmyzsh/ohmyzsh#3440) or include a shell function for pyenv in your zshrc that passes all arguments to pyenv and afterwards calls rehash (see top answer in https://stackoverflow.com/questions/34340575/zsh-alias-with-parameter).
