Installation de Tailwind css dans workflow gulp

Hello à tous

Je galère a ajouter Tailwind dans un workflow gulp.
J'obtiens cette erreur lors de la compilation

a écrit :

C:\xampp\htdocs\gulpy-toto\src\tw\main.css:2:25: The `text-white` class does not exist. If you're sure that `text-white` exists, make sure that any `@import` statements are being properly processed before Tailwind CSS sees your CSS, as `@apply` can only be used for classes in the same CSS tree.

Si quelqu'un pouvait m'aider. J'ai tourné en rond toute la journée et je sens que je suis prêt du but.

Merci !!!!!!!

Salut

Est-ce que tu pourrais montrer tes fichiers scss contenant Tailwind ? Ainsi que ta config Tailwind si tu en as une ?

J'ai reproduit une config gulp avec ton gulpfile.js et j'arrive à le faire tourner.

Donc pour le moment je pencherais vers ton ficher de config ou ton a.tailwind.scss.
