无法启动我的Node.js应用程序

Question

Hi I am trying to start a node-js based application but it is giving me some mongodb based error and I can't seem to start my plugin.

Error:

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

Here are the configurations I am currently using: database.js

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

app.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',
});

I am also using jugglingdb as crossDb ORM in my application

config.json

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

},

After I implemented the suggestions provided the errors has completely changed:

Answer 1

You didn't include any info on what is in line 56 of your app.js.

The error looks like the mongodb driver is trying to find a slash in a variable called host and fails to do so because the host is undefined.

Isn't it because you have var schema defined twice?

var schema = new Schema('mongodb');

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

Maybe remove the first one where you don't have the url .

Also, are you using both Mongoose and JugglingDB in the same program?
