error  in ./resources/sass/app.scss

Error: [object Object] is not a PostCSS plugin

I am not using PostCSS at all.

I upgraded to fix an issue with the manifest files being put in the wrong folder ( have not confirmed that it's solved for me )

Steps To Reproduce:

const mix = require('laravel-mix')
mix.sass('resources/sass/app.scss', 'css/')

I attempted to install PostCSS npm install postcss --save-dev and then I got a whole bunch of Babel errors so I reverted and now the error I have is [webpack-cli] Error: Cannot find module 'postcss'

[JamesFreeman]

I had this error too, I resolved it by running yarn add postcss --dev.

What were the Babel errors @adampatterson as you may have just moved the error on?

[adampatterson]

@iamthefreeman I tried that and it resulted in a tone of Babel errors.

I might try again and clear everything out.
