It is because tailwind documentation has changed, Please install tailwind with the new guidelines

But what happened to the tailwind.config.js?
Normally the init command created that file.

for anyone trying to use tailwindcss outside a npm project, you can install globally with:

how to install and configure tailwindCSS executable?

• tailwind docs

# download tailwind binary and move to "~/.tailwindcss/bin"
mkdir ~/.tailwindcss; cd ~/.tailwindcss/
mkdir bin; cd bin
# this works for arm64, check docs for other arch
curl -sLO https://github.com/tailwindlabs/tailwindcss/releases/latest/download/tailwindcss-macos-arm64
chmod +x tailwindcss-macos-arm64
mv tailwindcss-macos-arm64 tailwindcss

• add to your .zshrc or .bashrc:

# tailwindcss
export PATH=$PATH:~/.tailwindcss/bin

now you can use tailwindcss

tailwindcss --help

i am unable integrate the tailwind V4 by following the steps in the documentation. Here's what am getting
{C51F0455-AAF4-4C84-AEE4-8F0186698C51}

What Thank you so much for your helpful answer! It saved me a lot of time and pointed me in the right direction. I was unaware that the init command no longer exists in Tailwind v4, and your advice to use the version qualifier for v3 was exactly what I needed. I really appreciate your clear explanation and the time you took to provide this solution. Thanks again!

Thanks a lot dude! wasted 1 hour trying to resolve the issue

Steps are still present in the Jetbrains docs https://www.jetbrains.com/help/phpstorm/tailwind-css.html#ws_css_tailwind_install

If you see this, update your IDE to one with 2024年3月2日 (released this year) with the change from https://youtrack.jetbrains.com/issue/WEB-70442/Support-Tailwind-CSS-4

You should NOT need to run this command anymore, and get the tailwind.config.js. Just update your IDE.

still giving in ...thanks

Deprecated init process

In v4, the installation process has changed. It's now simpler. The init command has become obsolete and is no longer usable from v4 onwards because it's not needed anymore.

Source: Problem installing TailwindCSS with "npx tailwindcss init -p" command

Changed npx tailwindcss to npx @tailwindcss/cli

The command to run is now no longer npx tailwindcss but npx @tailwindcss/cli.

PostCSS plugin and CLI are separate packages — the main tailwindcss package doesn't include these anymore since not everyone needs them, instead they should be installed separately using @tailwindcss/postcss and @tailwindcss/cli.

Source: Open-sourcing our progress on Tailwind CSS v4.0 - Whats changed

This is basically only necessary if you're not using it with a framework and want to run it from the command line. For this, a standalone @tailwindcss/cli package will help from v4 onwards.

npm install tailwindcss @tailwindcss/cli

CSS-first configuration

CSS-First Configuration: Customize and extend the framework directly in CSS instead of JavaScript.

With TailwindCSS v4, you have the option to omit the tailwind.config.js file. You can find many new directives, such as @theme, which allows you to declare your custom settings directly in your CSS file, or @plugin, which lets you import TailwindCSS v4-compatible plugins directly in your CSS file.

I won't list all the new directives, but you can check them out here:

Source: What's the new CSS-first configuration

TailwindCSS v4 is backwards compatible with v3

Using a JavaScript config file

JavaScript config files are still supported for backward compatibility, but they are no longer detected automatically in v4.

If you still need to use a JavaScript config file, you can load it explicitly using the @config directive:

@config "../../tailwind.config.js";

• Using a JavaScript config file - TailwindCSS v4 Update Guide

The configuration setting has changed by default. However, you have the option to declare the location of your tailwind.config.js file using a relative path in your default CSS file so you can use it again.

I'm encountering some difficulties with the new installation flow.

In the previous version, everything was more straightforward and easy to configure...
Regardless of what I do, I couldn't achieve to get tailwind config file... I did everything according to "Nuxt" instructions for my Vue project, there's no section for VUE, (although both have the same bases so it supposed to be working..) -> https://tailwindcss.com/docs/installation/framework-guides

The doc should be more clear I found out about this change from this stack overflow post: https://stackoverflow.com/questions/79380514/problem-installing-tailwindcss-with-vite-after-npx-tailwindcss-init-p-comman/79380522#79380522

My question is: Is there a problem with the npm package? Coz I also got the same error like most people here... I think it can be improved, many people got issues, it shouldn't be that complicated or maybe because we're so used to the way it was...

Thanks , Great Knowledge transfer
