Erreur : le plug-in PostCSS tailwindcss nécessite PostCSS 8

Question

J'ai installé la nouvelle version 2.0 de tailwindcss et j'ai l'erreur suivante. J'ai essayé de désinstaller postcss et tailwindcss mais cela ne fonctionne pas. Besoin d'aide.

 
Module build failed (from ./node_modules/postcss-loader/src/index.js):
Error: PostCSS plugin tailwindcss requires PostCSS 8.

Answer 1

Vous intégrez Tailwind à un outil qui repose sur une ancienne version de PostCSS. Vous pouvez utiliser ce documenthttps://tailwindcss.com/docs/installation#post-css-7-compatibility-build

Answer 2

npm uninstall tailwindcss postcss autoprefixer

alors

 vue add tailwind 

pour utiliser le plugin vue cli https://www.npmjs.com/package/vue-cli-plugin-tailwind

Answer 3

a fonctionné pour moi :

 npm install tailwindcss@npm:@tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9

Answer 4

Cette solution ci-dessous devrait fonctionner parfaitement.

Exécutez les commandes suivantes

 npm uninstall tailwindcss postcss autoprefixer

npm install tailwindcss@npm:@tailwindcss/postcss7-compat @tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9

EDIT : Suppression de certains espaces erratiques.

Answer 5

Désinstallez Tailwind et réinstallez-le en utilisant la version de compatibilité à la place

 npm uninstall tailwindcss postcss autoprefixer
npm install tailwindcss@npm:@tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9
