poetry install reported python version and installed venv python version differ

[stohrendorf]

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: opensuse leap 15.3 / conda

• Poetry version: 1.1.6

• Link of a Gist with the contents of your pyproject.toml file: https://github.com/moneymeets/ghd/blob/6449eb2ef0cffe63d6f4ff2502ffab688c0305d4/docker/pyproject.toml

Issue

I used the new installer, which installed poetry using python 3.8.5. Additionally, I have installed conda, with a python 3.9.5 virtual environment, which is prefixed to $PATH so it is preferred over the system installed python version - this was added after installing poetry.

When doing a poetry install without any existing prior virtualenv, the following is printed to the console:

$ poetry install
The currently activated Python version 3.8.5 is not supported by the project (3.9.5).
Trying to find and use a compatible version. 
Using python3 (3.9.5)
Creating virtualenv ghd-m2Y1OWxf-py3.9 in /home/steffen/.cache/pypoetry/virtualenvs
Installing dependencies from lock file

Package operations: 55 installs, 0 updates, 0 removals
<<< snip >>>

poetry correctly reports that it uses python 3.9.5, as this exact version is specified in pyproject.toml. However...

$ /home/steffen/.cache/pypoetry/virtualenvs/ghd-m2Y1OWxf-py3.9/bin/python --version
Python 3.8.5
/usr/bin/python3 --version
Python 3.6.13
/home/steffen/.local/share/pypoetry/venv/bin/python3 --version
Python 3.8.5
$ which python3
/home/steffen/miniconda3/envs/python-3.9/bin/python3
$ python3 --version
Python 3.9.5

which is clearly not python 3.9.5. The creation of the virtualenv can be done correctly if I'm doing a poetry env use $(which python3), but this shouldn't be necessary as poetry reported it was using the correct version.

Hey,

this should now work correctly by setting virtualenvs.prefer-active-python to true.
