Just the stack trace is not useful for people helping you. Post your webpack config, commands you are trying to run, piece of code, etc. — PlayMa256

Add

const VueLoaderPlugin = require('vue-loader/lib/plugin')

to the top of your webpack config, and

new VueLoaderPlugin()

in your plugin section.

And for your style blocks, add:

      // this will apply to both plain `.css` files
      // AND `<style>` blocks in `.vue` files
      {
        test: /\.css$/,
        use: [
          'vue-style-loader',
          'css-loader'
        ]
      }

You might also try:

  extensions: ['', '.vue', '.js', '.jsx']

I have seen the order become an issue.
