node.js - 在 node-red 中没有生成节点

问题描述

我尝试通过创建新节点来解决 Node-red 中提出的问题：自定义节点等待丢失的类型。

我尝试使用“mqtt.js 示例”来获取预配置的 mqtt-client/subscriber 以添加到我的调色板中。

因此，在节点文件夹中，我有一个名为 mqttConfig.json 的配置文件，其中放置了 mqtt.js 用于建立连接的所有数据（即代理、主题、qos ...），该文件的结构是相同的和上一个一样。

{
  "receiver": {
               "broker":"127.0.0.1",
               "topic":"topicRec",
               "qos":"2"
              }
}

然后我创建新的 preconf_mqtt.js 即：

var mqtt = require("/usr/local/lib/node_modules/node-red/node_modules/mqtt");
var mqttConfig = require("mqttConfig");
'use strict'

module.exports = function(RED)
 {
  function ConfiguredMqttOutNode(config)
      {
       RED.nodes.createNode(this,config);
       var node = this;

       var m = mqttConf.receiver;

       this.topic = m.topic;
       this.qos = parseInt(m.qos);
       if (isNaN(this.qos) || this.qos < 0 || this.qos > 2)
          this.qos = 2;
       this.broker = m.broker;
       this.client = mqtt.connect(this.broker);
       this.client.subscribe(this.topic);

       this.client.on('message', function (topic, message) {
            var msg = {};
            msg.topic = this.topic;
            msg.payload = JSON.stringify(message);
            node.send(msg);
            });

  }
  RED.nodes.registerType("configured-mqtt-out",ConfiguredMqttOutNode);
 }

而 preconf_mqtt.html 即：

     <script type="text/javascript">
        RED.nodes.registerType('configured-mqtt-out',{
          category: 'processing',
          color: '#a6bbcf',
           defaults: {
           name: {value:""}
        },
         inputs:0,
         outputs:1,
         icon: "bridge.png",
         label: function() 
         {
           return this.name||"c-mqtt-out";
         }
        }); 
    </script>

    <script type="text/x-red" data-template-name="configured-mqtt-out">
       <div class="form-row">
          <label for="node-input-name"><i class="icon-tag"></i> Name</label>
          <input type="text" id="node-input-name" placeholder="Name">
       </div>
    </script>

    <script type="text/x-red" data-help-name="configured-mqtt-out">
        <p>Pre-configured MQTT subscriber</p>
    </script>

无论我何时尝试安装程序：

当我启动它时，node-red 没有显示任何特定的错误/警告：

但是该节点不在我的调色板中，我不知道该怎么做才能修复它。请帮帮我，亲切的问候， Gianluca

[编辑] 我忘了在包中添加节点：S 我有它，然后我收到以下警告，开始 node-red：

并且没有生成节点...
