[>] Checking Python 3 installation....(None)

[CGMossa]

I've tried quarto check and it cannot detect my python installation. I find that odd since I have python installed.
I've looked and there is nothing to configure or try otherwise.
I've tried

$env:QUARTO_PYTHON = "python"

Doesn't work either.

Here's the print of what I got:

I think the QUARTO_PYTHON variable needs to specify the path to the directory where your desired Python executable is installed

@francisbarton Thanks, but avoid replying to 3 years old zombie thread.

Thanks @francisbarton for your reply. Much appreciated to still help on unanswered topic!

@CGMossa sorry we missed your question 3 years ago. If you still have issue nowadays, read the updated doc. As mention in installation (https://quarto.org/docs/computations/python.html#installation), quarto will try to be clever to detect Python from PATH, or from virtual activated, but you can still set env var to a python filepath (so not $env:QUARTO_PYTHON = "python" as it will look for python locally to your project).

Running quarto check jupyter --log-level debug could give you hints on discovery, or quarto render --log-level debug (more in https://quarto.org/docs/troubleshooting/#verbose-mode)

Hope it helps. And please to share again if you still have troubles setting up.

Thank you both.
