Describe your issue

Following the instructions at https://tailwindcss.com/docs/installation I installed tailwind and then tried to run npx tailwindcss init and received an error saying Error: Cannot find module 'postcss'.

This is due to postcss-js v4 no longer taking a direct dependency on postcss https://github.com/postcss/postcss-js/commit/034b00a9ae1db85f7b628d0195c931938ddcb718.

I followed the Tailwind CLI steps which say to only install tailwindcss. After some more testing this looks to be an issue when using yarn but not when using npm.

Just learned that yarn doesn’t automatically install peer dependencies like npm (1, 2, 7+) does. Not sure how I haven’t hit this before, but that seems to be the cause here.

I think this should be re-opened - I’ve just run into the exact same issue.

The documentation for Tailwind CLI (https://tailwindcss.com/docs/installation) only mentions installing tailwindcss, but postcss is also needed to run npx tailwind init (on the next line).

(Using NodeJS v16.13.2, Tailwind CSS 3.0.19, npm 8.1.2)
