您正在运行没有模板编译器的仅运行时构建。

You are running a runtime-only build without the template compiler.

签出 https://vuejs.org/v2/guide/installation.html#Webpack

你需要为'vue'创建一个别名，所以webpack包含来自你node_modules /的正确的vue / dist / *。js：

You need to create an alias for 'vue', so webpack includes the correct vue/dist/*.js from your node_modules/:

module.exports = {
  // ...
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    }
  }
}
