Solution 1
You're integrating Tailwind with a tool that relies on an older version of PostCSS. You can use this doc https://tailwindcss.com/docs/installation#post-css-7-compatibility-build
Solution 2
npm uninstall tailwindcss postcss autoprefixer
then
vue add tailwind
to use the vue cli plugin https://www.npmjs.com/package/vue-cli-plugin-tailwind
Solution 3
worked for me :
npm install tailwindcss@npm:@tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9
Solution 4
This solution below should work perfectly.
Run the following commands
npm uninstall tailwindcss postcss autoprefixer
npm install tailwindcss@npm:@tailwindcss/postcss7-compat @tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9
EDIT: Removed some erranous spaces.
Solution 5
I was getting dependency tree error when I try uninstall and install with compact version. So I had to install with yarn
instead and it works.
npm uninstall tailwindcss postcss autoprefixer
yarn add tailwindcss@npm:@tailwindcss/postcss7-compat postcss@^7 autoprefixer@^9

I installed the new tailwindcss version 2.0 and I've got the following error. I tried to uninstall postcss and tailwindcss but it does not work. Need help.
