<template><div id="app"><HelloWorld msg="Welcome to Your Vue.js App"/></div>
</template><script>
import HelloWorld from './components/HelloWorld.vue'export default {name: 'app',components: {HelloWorld}
}
</script><style>

}
ul {list-style-type: none;padding: 0;

}
</style>

总结：

1. assets目录下的资源文件在使用时要用require() 处理下，因为webpack打包时路径发生了变化！
