How to upgrade Python version from 3.8.2 to 3.8.5 for an existing poetry environment?

How to upgrade Python version for existing poetry environment?

Issue

I manage Python versions via pyenv. But I can’t convince poetry to load Python 3.8.5 when the environment is activated. It keeps using 3.8.2.

➜  my-project python -V
Python 3.8.5

➜  my-project pyenv versions
* 3.8.5 (set by /home/raffael/PycharmProjects/my-project/.python-version)

➜  my-project poetry shell 
Spawning shell within /home/raffael/.cache/pypoetry/virtualenvs/my-project-L-QBB5_N-py3.8

➜  my-project . /home/raffael/.cache/pypoetry/virtualenvs/my-project-L-QBB5_N-py3.8/bin/activate

(my-project-L-QBB5_N-py3.8) ➜  my-project python -V
Python 3.8.2

(my-project-L-QBB5_N-py3.8) ➜  my-project pyenv shell 3.8.5

(my-project-L-QBB5_N-py3.8) ➜  my-project pyenv local 3.8.5

(my-project-L-QBB5_N-py3.8) ➜  my-project python -V
Python 3.8.2

(my-project-L-QBB5_N-py3.8) ➜  my-project poetry env use 3.8.5
Using virtualenv: /home/raffael/.cache/pypoetry/virtualenvs/my-project-L-QBB5_N-py3.8

(my-project-L-QBB5_N-py3.8) ➜  my-project python -V           
Python 3.8.2

Isn’t that a tiny bit ironic that a dependency management system for Python cannot manage the most central dependency - that of the interpreter itself?

Apparently pyenv uses shivs to intercept and reference to python so that it can point to its versions, but this doesn’t work when poetry calls python. In my case it is using the default system python version 3.8.5 when the global pyenv version I have is 3.8.10. There is no way for me to change the version poetry uses the version I set using pyenv.

Please can poetry link with pyenv somehow so that poetry uses the pyenv version I set as default?
