Will keep it open there as this doesn't relate to Next.js internals.

@timneutkens be aware that because next 9.0.7 now forces css-loader 3.2.0, anyone that uses @zeit/next-css will run into that issue. So i think it should be top priority. I would also like to see a migration path from css-loader to the new experimental css feature.

+1, happening with @next/less for me.

Please try next@v9.0.8-canary.3 -- this version should fix these broken plugins.

I got this error using 9.0.7 and @zeit/next-sass, 1.0.1 when I upgrade to next@v9.0.8-canary.3 I get Module not found: Can't resolve 'css-loader/locals'

[Timer]

@retallicka please provide a reproduction.

@retallicka a fix should be up in #8957; I found the source of this loader.

[Timer]

Please give v9.0.8-canary.4 a try.

Works well with next@9.0.8-canary.4 and css-loader@2.2.0

[nns2009]

I confirm for 'next-sass'
"@zeit/next-sass": "^1.0.1"
produced the same error with next@9.0.7,
but works with next@9.0.8-canary.4
