How to fix the `unable to resolve dependency tree` PostCSS and Tailwind issue in Next.js
How to solve the `unable to resolve dependency tree` error while installing Tailwind in a Next.js website
While setting up a new Next.js project with Tailwind I ran into an issue.
This issue might just be a temporary issue due to configuration problems and libraries versions, but I’m writing this in case someone stumbles on it.
I ran:
npm install tailwindcss postcss-preset-env postcss-flexbugs-fixes
In other words, PostCSS 8.1.13 was required but Next installed 8.1.7.
So I ran
npm install tailwindcss@latest postcss@latest
postcss-preset-env postcss-flexbugs-fixes
and it worked!
