Virtual env name doesn't show after reloading zsh

[Viet Nguyen]

Too many issues will kill our team's development velocity, drastically.
Make sure you have checked all steps below.

Prerequisite

• Make sure your problem is not listed in the common build problems.
• Make sure no duplicated issue has already been reported in the pyenv-virtualenv issues. You should look in closed issues, too.
• Make sure you are not asking us to help solving your specific issue.
  • GitHub issues is opened mainly for development purposes. If you want to ask someone to help solving your problem, go to some community site like Gitter, StackOverflow, etc.
• Make sure your problem is not derived from packaging (e.g. Homebrew).
  • Please refer to the package documentation for the installation issues, etc.
• Make sure your problem is not derived from other plugins.
  • This repository is maintaining the pyenv-virtualenv plugin only. Please refrain from reporting issues of other plugins here.

Description

• Platform information (e.g. Ubuntu Linux 20.04): OSX
• OS architecture (e.g. amd64): M1
• pyenv version: 2.2.5
• pyenv-virtualenv version: 1.1.5
• Python version: 3.10
• [N/A] virtualenv version (if installed):
• [N/A] Please attach the debug log of a faulty Pyenv invocation as a gist
  • If the problem happens in a Pyenv invocation, you can turn on debug logging by setting PYENV_DEBUG=1, e.g. env PYENV_DEBUG=1 pyenv install -v 3.6.4
  • If the problem happens outside of a Pyenv invocation, get the debug log like this:

    export PS4='+(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]:+${FUNCNAME[0]}(): }'
    set -x
    <reproduce the problem>
    set +x
    

If I start my virtual environment for the first time, I can see it:

(my-env) user@machine %

However, if I reload my zsh:

source ~/.zshrc

The name disappears even though the env is still activated

user@machine %

I can only check with:

pyenv virtualenvs

I added a custom script in my .zshrc to show the virtual env name after reloading.
