VSCode doesn't show poetry virtualenvs in select interpreter option

You just need to type in your shell:

poetry config virtualenvs.in-project true

The virtualenv will be created inside the project path and vscode will recognize.

You need to set "python.venvPath": "C:\\Users\\Jaepil\\AppData\\Local\\pypoetry\\Cache\\virtualenvs" in your settings (the one you tried is for UNIX).

You can also https://github.com/microsoft/vscode-python/issues/8372 to help prioritize adding Poetry virtual environment support to the Python extension.
