Hi there,

and thanks for you amazing work.

Since upgrading to 0.8.0 (was working with 0.7) I can not run npm run hot anymore

It is not just hot that breaks. I get exactly the same error when I run npm run dev.

[maiolica]

Can confirm npm run dev is broken since 0.8.0.

[kohenkatz]

Running npm install autoprefixer fixes it, but it really shouldn't be broken out of the box.

[rderimay]

Yep. Can confirm that npm install autoprefixer solves the problem :-)

[thijskok]

It looks like downgrading the css-loader version requirement causes the autoprefixer package to be absent?

The older css-loader requires an older version of cssnano, which in turn doesn't require the autoprefixer yet. I guess it should be added to the Laravel-Mix package.json, though.

Hmm - weird that I never saw this error.

Anyways, I've just tagged 0.8.1 that adds autoprefixer as a dependency. Thanks guys!
