Maybe my expectation of pyenv virtualenv with miniconda is plain wrong and it is expected to not work ? My naive assumption is that I can create a virtualenv of any installed python interpreter.

Looks like the virtualenv is using some other previously installed miniconda ( miniconda3-latest in my case ).

To remove this warning, please choose a default channel explicitly with conda's regular configuration system, e.g. by adding 'defaults' to the list of channels:

  conda config --add channels defaults

It's more like conda uses some metadata cache in a shared location.

The immediate reason is the conda command pyenv-virtualenv runs: conda create <...> --yes <..> python Which makes it use the latest Python in its metadata.

We should probably read the version of the Python package in the base environment and instruct it to install that.
