在我的應用程序，當我嘗試打電話給我收到錯誤像這樣的服務：`npm`錯誤爲'錯誤：無法找到module` - 如何解決
module.js:327
throw err;
^
Error: Cannot find module '/api/sessions'

[14:38:53] [nodemon] app crashed - waiting for file changes before starting...
這裏是我的server.js文件：
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(express.static(__dirname + '/assets'))
app.use(express.static(__dirname + '/templates'))
app.use(bodyParser.json());
//if i remove both this 2 lines, no issues come.
app.use(require('/api/sessions', require(__dirname + '/controllers/api/sessions')));
app.use(require('/api/users', require('./controllers/api/users')));
app.get('/', function(req, res){
res.sendFile(__dirname + '/layouts/app.html');
})
app.listen(8888, function(){
console.log('app listening!' + 8888);
})
這裏有什麼問題，如何解決這個問題。這兩個文件無非是從前端處理查詢。
session.js樣品：只使用
var router = require('express').Router();
var bcrypt = require('bcryptjs');
var jwt = require('jwt-simple');
var User = require('../../models/user');
var config = require('../../config');
router.post('/sessions', function(req, res, next) {
User.findOne({
username: req.body.username,
}).select('password').select('username')
.exec(function(err, user) {
if(err) { return next(err)}
if(!user) { return res.send(401)}
bcrypt.compare(req.body.password, user.password, function(err, valid) {
if(err) { return next(err)}
if(!valid) { return res.send(401)}
var token = jwt.encode({username:user.username}, config.secret);
res.send(token);
})
})
});
module.exports = router;
