python.poetryPath default setting isn't working on Windows

See original GitHub issue

Environment data

VS Code version: 1.14.1
Extension version (available under the Extensions sidebar): 2020.1.58038
OS and version: Windows 10
Python version (& distribution if applicable, e.g. Anaconda): 3.8.1
Type of virtual environment used (N/A | venv | virtualenv | conda | …): in project .venv
Relevant/affected Python packages and their versions: poetry v1.0.2 ‘in the path’
Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info #3977): both

Expected behaviour

poetry add --dev pylint

Actual behaviour

python -m pip install pylint

Steps to reproduce:

poetry init
poetry install
create a python file
the python extension start and activate the virtualenv as expected
popup that inform no linter found in venv, ask to install
this will install linter without poetry

The default python.poetryPath is set to poetry and this is fine on linux; on windows however, though the executable is in the path and is actually poetry, it is called by the poetry.bat file this means that the right python.poetryPath for windows had to be set to poetry.bat

This isn’t really a big issue, maybe can only be explicit as a settings reference

Spike results

Due to an upstream Windows only bug on node https://github.com/nodejs/node-v0.x-archive/issues/2318 (also see stack overflow answer), child_process.spawn fails to run files without any extension. poetry file inside %USERPROFILE%/.poetry/bin is not an executable, hence spawning it via child_process fails. It is documented shell: true may help us out there, but using it doesn’t return any output for the command for some reason.

The easiest option is just to use child_process.exec instead of child_process.spawn to run poetry, which is provided via https://github.com/microsoft/vscode-python/blob/3a7c11cee5953eb39e666ee441df99d99cda6ac9/src/client/common/process/proc.ts#L60

It works fine both for poetry and poetry.bat files.

Maybe we shouldn’t let poetryPath point to the bat file.

I think we could prompt an error saying:

“The path to poetry is invalid. Please point it to the executable file.”

What do folks here think?
