Error: Cannot find module 'autoprefixer-core'

I followed the instructions in your readme and it ends up with this error message:

Error: Cannot find module 'autoprefixer-core'

@verpixelt It's not gulp-postcss issue. Maybe you forgot to npm i autoprefixer-core?
Also I recommend to use autoprefixer module instead of autoprefixer-core. The last will be deprecated soon.

[verpixelt]

Might be the issue. Would be good to add this as a dependency to the README file (at least make it clearer).

@verpixelt Cannot find module 'autoprefixer-core' means you do require without downloaded module. You require nothing.

Yeah, maybe a line that says that you have to install processors separately, with a link to a list of them will be helpful.

Thanks @w0rm :) 👍 That's really helpful! ☀️
