Think we’ve got a solution to this for now. We’re going to publish a PostCSS 7 compatible version as well under a “compat” tag:
npm install tailwindcss@compat
...if you’re using a framework that hasn’t upgraded yet.
Nice thing is we’re able to do it in the same branch.
Crazy how few tools are compatible with PostCSS 8 yet :/ Create React App is the latest one I'm running into. Really thinking we will have to stick to PostCSS 7 for Tailwind 2.0 or no one is going to be able to even use it.
