I got a task to do which is to create some forms with tailwindcss but When I try to launch : npm run build, it does't work. Could you help me?

npm ERR! code ELIFECYCLE
npm ERR! errno 9
npm ERR! widgets@1.0.0 dev: `tailwind build css/tailwind.css -o build/css/tailwind.css`
npm ERR! Exit status 9
npm ERR! 
npm ERR! Failed at the widgets@1.0.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
