Issue

Using the old get-poetry.py installer script to install Poetry, I can install projects globally by setting poetry config virtualenvs.create false (e.g. see #243). This is useful for installing projects in a Docker container.

Using the new install-poetry.py installer, it looks like the script creates a virtualenv at ${XDG_DATA_HOME}/pypoetry/venv (~/.local/share/pypoetry/venv by default) inside of which Poetry is installed. Based on my understanding, this also means that projects will be installed within this venv instead of globally. I'm not sure if I'm missing something, but how can we do a global install with the new installer?

This is the same problem as #4187.

Feel free to close as duplicate, but I'm keeping it open for now as this issue is about global installs vs strictly about virtualenvs.create which may or may not be working as intended depending on how you look at it.

Yes, this should be a duplicate of #4187.
