Poetry does not use active pyenv when creating virtual environment

• I am on the latest Poetry version.

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

• OS version and name: MacOS 10.14 Mojave

• Poetry version: 0.12.8

Issue

I have a project directory with a .python-version file like this:

3.7.1

Poetry has been installed into Python 3.6.5. According to recent comments, poetry is supposed to detect the active Python version when creating a new virtual environment, but it seems to stick with 3.6.5 all the time. To illustrate:

$ python --version
Python 3.7.1
$ poetry run python --version
Python 3.6.5

When I specify python = "^3.7" in `pyproject.toml I get an error:

$ poetry shell

[RuntimeError]
The current Python version (3.6.5) is not supported by the project (^3.7)
Please activate a compatible Python version.

shell

Thanks @princelySid. That would be poetry env use $(pyenv which python) for pyenv users with an active pyenv interpreter.

poetry installed with install-poetry.py to enable poetry self update. Same problem with pyenv python version.

It seems to work with explicit virtual env creation with:

poetry env use -- $(which python)

# Creating virtualenv ...-VfhLuGbT-py3.7 in .../.cache/pypoetry/virtualenvs
# Using virtualenv: .../.cache/pypoetry/virtualenvs/...-VfhLuGbT-py3.7
