Looks like an npm 6 package hoisting bug (works in npm 7).

Because postcss 8 is listed as a dependency of @vue/cli-serivce, at the same level as autoprefixer.

vue-cli/packages/@vue/cli-service/package.json

Line 67 in 40e3de2

"postcss": "^8.2.6",

Seems fixable by bumping cssnano version to v5.0.0-rc.1

@sodatea It looks like, despite the fix, alpha.7 has the same issue with the exact same repro.

npm list poscss gives:

🤯 It was fixed when I tried that PR locally…

Maybe we do need a postcss dependency in the project root at the moment.

No easy way. I would recommend against doing so.

@sodatea Is there any timeline on when we'll have postcss8 support?

Vue CLI v5 alpha has already supported PostCSS 8.
