Question

我正在尝试按照本教程制作节点api

https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens

问题在于我执行时

$ nodejs server.js

我收到此错误

{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }
js-bson: Failed to load c++ bson extension, using pure JS version
{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }

我的目录结构是

- sou/
----- models/
---------- user.js
- config.js
- package.json
- server.js

我的server.js是

// =======================
// get the packages we need ============
// =======================
var express     = require('express');
var app         = express();
var bodyParser  = require('body-parser');
var morgan      = require('morgan');
var mongoose    = require('mongoose');

var jwt    = require('jsonwebtoken'); // used to create, sign, and verify tokens
var config = require('./config'); // get our config file
var User   = require('./sou/models/user'); // get our mongoose model

// =======================
// configuration =========
// =======================
var port = process.env.PORT || 8080; // used to create, sign, and verify tokens
mongoose.connect(config.database); // connect to database
app.set('superSecret', config.secret); // secret variable

// use body parser so we can get info from POST and/or URL parameters
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

// use morgan to log requests to the console
app.use(morgan('dev'));

// =======================
// routes ================
// =======================
// basic route
app.get('/', function(req, res) {
    res.send('Hello! The API is at http://localhost:' + port + '/api');
});

// API ROUTES -------------------
// we'll get to these in a second

// =======================
// start the server ======
// =======================
app.listen(port);
console.log('Magic happens at http://localhost:' + port);

my models / user.js

// get an instance of mongoose and mongoose.Schema
var mongoose = require('mongoose');
var Schema = mongoose.Schema;

// set up a mongoose model and pass it using module.exports
module.exports = mongoose.model('User', new Schema({
    name: String,
    password: String,
    admin: Boolean
}));

我错过了什么？

感谢

Answer 1

这个答案大多在评论中得到解决。这是最终的解决方案。

首先，项目目录不正确，所需的文件不是它应该的位置。修复require语句修复了这个问题。

其次，服务器无法连接到mongodb服务器。确保mongo服务器正在运行，并且应用服务器具有正确的连接详细信息修复此问题

希望我帮忙！
