i'm not able to use the , 'npm install -D tailwindcss postcss autoprefixer' in my frontend(react/vite). So whenver i use this command along with 'npm i tailwindcss@latest ' . so my tailwindcss starts working with only this cmd: 'npm i tailwindcss@latest', but this following cmd : 'npm install -D tailwindcss postcss autoprefixer', gives error :npx tailwindcss init -p >> 'tailwind' is not recognized as an internal or external command, operable program or batch file. or says not in your local directory or cant find the tailwindcss version also , my ultimate goal is to get these files frontend/ tailwind.config.js postcss.config.js , but i'm very specific to this cmd : 'npm install -D tailwindcss postcss autoprefixer' it does n't work at all , getting error like this: PS D:\daily_practice\frontend> npx tailwindcss init -p >> npm error could not determine executable to run npm error A complete log of this run can be found in: C:\Users\rahul\AppData\Local\npm-cache_logs\2025-10-29T05_01_47_218Z-debug-0.log PS D:\daily_practice\frontend> getting this error again getting this , SO MY QUESTION IS AFTER THIS COMMAND : 'npm i tailwindcss@latest' tailwindcss starts working but this cmd never works and gives error:'npm install -D tailwindcss postcss autoprefixer', which if executed correctly gives these files: tailwind.config.js postcss.config.js , SO IS THIS COMMAND NOT NEEDED IN VITE/REACT ANYMORE OR WHY I'M FACING THIS ISSUE ?
