title: There is no webpack.mix.js in my node_modules
body: <p>After installing laravel mix via terminal and running the command cp node_modules/laravel-mix/setup/webpack.mix.js ./ I'm getting this error.</p>
  <pre><code>cp : Cannot find path 'C:\Users\COBNETCKNN\Local Sites\portofolio\app\p

  <p>I also looked inside <code>node_modules/laravel-mix/setup/</code> and there was no <code>webpack.mix.js</code> so I couldn't pull it from there, did the directory changed or what happened? Can I copy <code>webpack.mix.js</code> from my previous projects and modify it for my needs?</p>
