// this kind of error also happens when I use the passport.js to build the use authentication.
// the main reason is that I have imported the user model in a wrong way:

var mongoose = require('mongoose');
var User = mongoose.model('User');
// rather than:
var User = require('../users');
// for I have compiled the Schema to the model using:
mongoose.model('User', UserSchema);
// and I did not use code below:
module.exports = mongoose.model('User', userSchema);

We can using arrow and select button to find out whether the lines are space or tab
