Poetry install in `my-new-extension` returns `virtualenv: error: argument --prompt: expected one argument`

[ReneTC]

Following the guide in the readme. You are guided to execute:

cd my-new-extension
poetry install

I get

usage: virtualenv [--version] [--with-traceback] [-v | -q] [--read-only-app-data] [--app-data APP_DATA] [--reset-app-data] [--upgrade-embed-wheels] [--discovery {builtin}] [-p py] [--try-first-with py_exe]

                  dest
virtualenv: error: argument --prompt: expected one argument

is it just me?
