群主，在执行gulp后报错，问题可能性缩小到gulpfile.js文件中 .webpack('app.js') 部分
如果删除这部分，命令行运行正常，浏览器控制台也不会出现任何错误提示
声明，近几次的反复尝试，没有添加任何样式合并文件。
其中 resources/assets/js/app.js应该是vue自带的js文件，之前的错误和当下的错误应该都是由它引起的，但不知道为什么群主视频中却没有这样的错误出现？

组件里的确有个字符的问题，改后，组件使用正常。
虽然组件使用正常了，但是前天遇到 的报错又在控制台里出现了？？
Laravel和前端那些事 视频里面没有遇到这种问题
报错如下：

没发现哪里写的不对？目前就是不确定是不是es6语法引起的？
你这里的command 什么意思
视频中操作两大部分：
1、调入es6语法
2、编辑和注册组件
最后执行 gulp

创建组件
<template>
    <button 
        class="btn btn-default"
        v-text="text"
    ></button>
</template>

<script>
    export default {
        mounted() {
            this.$http.post('/api/question/follower',{})
            .then(response=>{
                console.log(response.data);
            })
        },
        data() {
            return {
                followed: false
            }
        },
        computed: {
            text() {
                return this.followed ? '已关注' ：'关注该问题'
            }
        }
    }
</script>

注册组件

require('./bootstrap');

Vue.component('example', require('./components/Example.vue'));
Vue.component('question-follow-button', require('./components/QuestionFollowButton.vue'));

const app = new Vue({
    el: '#app'
});

gulpfile.js 在phpStrom里提示错误

elixir((mix) => {
    mix.sass('app.scss')
       .webpack('app.js');
});

这里我添加 button 组件，但是没有显示show视图里没有显示这个按钮
另外，组件已经注册 执行了gulp ，代码中也没有任何错误提示？
好像执行gulp时有报错，这个报错看不懂？？

另外视频中调出es6语法的快捷键是什么？

这里用Repository模式， 同我之前用的service+store层差不多，我原来的service层专门处理代码逻辑，store执行数据库操作

public function topics()
    {
        return $this->belongsToMany('App\Models\Topic')->withTimestamps();
    }

这里有问题，我至于具体是哪？我也不知道，我从文档中复制了这句就对了？
当然 Topic::calss 也是正确的

Question::where('id',$id)->first();
这 样是没有问题的
其实很多东西我都学过，只是理解不深刻或是没记住。我会抓紧时间看群主的视频，比我以前学习的例子好很多。

http://www.zt.com/questions/2
浏览器输入上面内容时，出现下面报错：
Call to undefined relationship [topics] on model [App\Models\Question].
检查控制器及model没发现问题
Question model

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Question extends Model
{
    protected $fillable = ['title', 'body', 'user_id'];

    /**
     * 定义多对多关系
     */
    public function topics()
    {
        return $this->belogsToMany(Topic::class)->withTimestamps();
    }
}

QuestionsController 控制器

public function show($id)
    {
        // 使用 with 方法指定想要预载入的关联对象 预载入可以大大提高程序的性能
        // 这里的 topics 是App\Models\Question 中的 topics 的方法
        $question = Question::where('id',$id)->with('topics')->get();

        // compact 创建一个包含变量名和它们的值的数组
        return view('questions.show',compact('question'));
    }

你这里如果没有从后台返回数据，前端用户输入的数据会生成话题吗？我这里从后台返回话题数据正常，但生成话题却不行？

问题解决

我基础差，有很多不足，我目前想先按自己基础水平跟着实战项目走遍，然后记录下所有的问题，这样子我觉得学习会更直接全面些。很多时候都是盲目在学，也不了解实际运用。多有烦扰，请见谅！
