1.2.0 fails to recognise external active virtualenv

• Poetry version: 1.2.0
• Python version: 3.8.x
• OS version and name: ubuntu 22.04 and macOS 12.5
• pyproject.toml: any

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

External envs are not correctly detected by poetry 1.2.0

to reproduce (with default poetry config)

rm -rf /tmp/venv/ && python3 -m venv  /tmp/venv && . /tmp/venv/bin/activate && poetry install -v

shows: Creating virtualenv ${poetry_project_name}-Wz7GVy6b-py3.8 in /Users/myuser/Library/Caches/pypoetry/virtualenvs

when poetry config virtualenvs.create false is set the above command produces:

Skipping virtualenv creation, as specified in config file.

as one can see poetry is trying to install to the system instead of the activated venv and fails (as expected) due to permissions

poetry env info doesn’t show paths to the activated external venv:

Its worth nothing that everything works for me as expected on macOS as well. I’m going to close this for now as neither of us can reproduce it reliably – I suggest you inspect the shell environment after activate to make sure VIRTUAL_ENV and PATH are set correctly (local configuration is likely what is at fault for you here).

Our virtual environment detection mechanism is a bit complex as we do have a class-based Env that’s used to do handling of different types of environment – that being said, I’m not 100% sure what you mean.
