tailwindCSS 설치 시 에러

npm error could not determine executable to run

지난번에도 이거때문에 고생을 좀 했었는데(윈드서프가 알아서 해줌 ,,,근데지금은 크레딧이 없어 내가)
이번에도 또 떠서
도대체뭐냐!!!!
하고 파봤음

배경

새 프로젝트 생성하고 tailwindcss 세팅하려고 하면 에러가 남.
npm error could not determine executable to run 이라는 에러가...

시도1 (뻘짓함)

이것도 뭔가 서치해서 보다가 이거라고해서 해봤는데

안됨 ㅋㅋㅋ

PS C:\Users\ASUS\Desktop\dashboard> npx @tailwindcss/cli -i ./src/input.css -o ./src/output.css --watch
Need to install the following packages:
@tailwindcss/cli@4.0.6
Ok to proceed? (y) y

≈ tailwindcss v4.0.6

Specified input file `.\src\input.css` does not exist.

시도2

결국은 버전 문제였다.

이거 참조함

PS C:\Users\ASUS\Desktop\dashboard> npm uninstall tailwindcss

Created Tailwind CSS config file: tailwind.config.js
Created PostCSS config file: postcss.config.js

지우고 다시 깔때 @3버전으로 콕 찝어서 설치해주면
해당 명령어도 잘 실행되고 config 파일도 생성된다.
