javascript - 无法启动我的 nodejs 应用程序

Question

您好，我正在尝试启动一个基于 node-js 的应用程序，但它给了我一些基于 mongodb 的错误，我似乎无法启动我的插件。

错误:

/home/jira-Plugins/cloud/test-plugin/node_modules/mongodb/lib/server.js:110
  if(host.indexOf('\/') != -1) {
          ^
TypeError: Cannot call method 'indexOf' of undefined
    at new Server (/home/jira-Plugins/cloud/test-plugin/node_modules/mongodb/lib/server.js:110:11)
    at new MongoDB (/home/jira-Plugins/cloud/test-plugin/node_modules/jugglingdb-mongodb/lib/mongodb.js:51:18)
    at Object.initializeSchema [as initialize] (/home/jira-Plugins/cloud/test-plugin/node_modules/jugglingdb-mongodb/lib/mongodb.js:26:22)
    at new Schema (/home/jira-Plugins/cloud/test-plugin/node_modules/jugglingdb/lib/schema.js:106:13)
    at Object.<anonymous> (/home/jira-Plugins/cloud/test-plugin/app.js:56:14)
    at Module._compile (module.js:456:26)

    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:902:3

以下是我目前使用的配置:数据库.js

module.exports = {
    url : 'mongodb://localhost/test'
};

应用程序.js:

var mongoose = require('mongoose');

/*var methodOverride = require('method-override'); // simulate DELETE and PUT (express4)*/
var database = require('./config/database');
/*var port     = process.env.PORT || 8888;*/         // set the port

mongoose.connect(database.url);
console.log('Connected to Database: ' + database.url);

var Schema = require('jugglingdb').Schema;
var schema = new Schema('mongodb');

var schema = new Schema('mongodb', {
  url: 'mongodb://localhost/test',
});

我还在我的应用程序中使用 jugglingdb 作为 crossDb ORM

配置.json

"store": {
  "adapter": "jugglingdb",
  "type": "mongodb"

},

如果错误已完全改变，我实现建议后:

Answer 1

您没有在 app.js 的第 56 行包含任何信息。

该错误看起来像是 mongodb 驱动程序试图在名为 host 的变量中查找斜杠，但由于 host 未定义而未能找到。

不是因为你定义了两次 var schema 吗？

var schema = new Schema('mongodb');

var schema = new Schema('mongodb', {
  url: 'mongodb://localhost/test',
});

也许删除第一个你没有url的。

此外，您是否在同一个程序中同时使用 Mongoose 和 JugglingDB？
