Error 'could not determine executable to run' when initializing Tailwind CSS in a Vite React project

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm setting up Tailwind CSS in a React project using Vite and encountered an error. Here's what I've done so far:

Installed the required dependencies:

BASH
npm install -D tailwindcss postcss autoprefixer vite

Then I attempted to initialize Tailwind CSS with:

BASH
npx tailwindcss init -p

However, I received the following error:
npm error: could not determine executable to run

Screenshot of the error: error image

Environment details:

Windows 11
Node.js version: v22.13.1
npm version: 10.9.2

I expected the above command to generate both the tailwind.config.js and postcss.config.js files. How can I resolve this issue and proceed with my setup?

Below is one working solution that others have reported as resolving this issue:

Run with the “ignore existing” flag
Sometimes npx mistakenly picks up a cached or conflicting version. Running:
```
BASH
npx --ignore-existing tailwindcss init -p
```
forces npx to use the locally installed version from node_modules.
Alternatively, call the executable directly
If the above still fails, you can execute the binary from your project's local bin folder:
```
BASH
./node_modules/.bin/tailwindcss init -p
```
Double-check your installation and versions
- Confirm that you have installed Tailwind CSS, PostCSS, and autoprefixer as dev dependencies:
```
BASH
npm install -D tailwindcss postcss autoprefixer
```
- Ensure you’re running the command from the project root.
- Occasionally, certain npm versions might cause issues with npx. If the problem persists, consider clearing the cache with npm cache clean --force or even temporarily downgrading npm.

Using one of these methods should generate the configuration files (tailwind.config.js and postcss.config.js) as expected and allow you to proceed with your Tailwind CSS and Vite setup.
