我的后端将消息推送到 rabbitmq 队列，我需要获取这些消息以显示在消息的前端部分，因为消息必须按特定顺序排列，我不能使用异步方法。

我写了这段代码

var open require("amqplib").connect("amqp://guest:guest@localhost:5682");
var queue = "developer";

export default {
    name: 'Subsriber',
    data: function() {
        return {
            selected: "",
            services: [],
        }
    },
    mounted() {
        var url = "http://10.0.9.134:5060/services/scripts";
        this.services = []; // empty the existing list first.
        setTimeout(() => {
            axios.get(url)
            .then(response => {
            this.services = response.data;
            })
        }, 2000)

        open.then(function(conn){
            return conn.createChannel();
        }).then(function(ch){
            return ch.assertQueue(queue).then(function(ok){
                return ch.consume(queue, function(msg){
                    if (msg != null){
                        console.log(msg.content.toString());
                    }
                });
            });
        });

    }

但我收到此错误：
