npm error when trying to initialize tailwindcss: "could not determine executable to run"

[SUPERNOOB20]

Hi, tailwind friends! Pleased to meet you all ^^)/

I use the Flask Python framework for web development, and I was trying to get tailwindcss to work with it.

I was following this tutorial: https://www.codewithharry.com/blogpost/using-tailwind-with-flask

But ended up getting stuck here (in the green-highlighted part):

I don't think the log can be all too helpful, but here you have it, just in case:
2025-05-16T09_09_07_727Z-debug-0.log

Do you have any idea of what the issue might be, or any other way of setting up tailwindcss for Flask? At any rate, please let me know! ^-^

The init command no longer exists in the most recent major version of Tailwind. Consider checking the installation documentation that is most relevant to your project to integrate Tailwind CSS properly.

If you are trying to use v3, ensure the version qualifier is used:

$ npm install -D tailwindcss@3
$ npx tailwindcss init

TLDR (for init process): Since v4, there is no need for a tailwind.config.js file, so the init process is also unnecessary, making both outdated. Review the v4 installation guides, where the init step is not included. Or install v3 with specifically changed guide.

TLDR (for Tailwind CLI): Previous content + In v4, Tailwind CLI was separated from the core package, so an additional package needs to be installed see below and in How to use Tailwind CLI.
