Technically, you can bring back poery shell with the command poetry self add poetry-plugin-shell.

I do agree it's a bit clunky, but here are some options for future readers for the time being -

Windows:
If you go into a project and type / paste & "$(poetry env info --path)\Scripts\Activate.ps1" that will enter the project.

With that, you can add a function to your PowerShell profile.

1. Open profile notepad $PROFILE
2. Add a function

function psh {
    & "$(poetry env info --path)\Scripts\Activate.ps1"
}

Linux and Mac

1. Edit your ~/.bashrc or ~/.zshrc
2. Add this

psh() {
  source "$(poetry env info --path)/bin/activate"
}

The above was tested on Poetry 2.1.2.

Thank you.

Thanks 😺
