我对node.js和Express 全新。我想用用户管理构建一个应用程序。我咨询了 stormpath 网站（https://stormpath.com/blog/build-nodejs-express-stormpath-app） 和应用程序的构建和显示如下：
当我点击立即注册和立即登录时，会出现错误：
The Register Error Screen shot
我完全按照教程， server.js 如下：
var express = require('express');
var stormpath = require('express-stormpath');
var app = express();
app.set('views', './views');
app.set('view engine', 'jade');
app.use(stormpath.init(app, {
expand: {
customData: true
}
}));
app.get('/', stormpath.getUser, function(req, res) {
res.render('home', {
title: 'Welcome'
});
});
app.use('/profile',stormpath.loginRequired,require('./profile')());
app.on('stormpath.ready',function(){
console.log('Stormpath Ready');
});
app.listen(3000);
index.jade 如下所示：
html
head
title=title
link(href='//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css',
rel='stylesheet')
body
div.container
div.jumbotron
h1 Release Control System
if user
p Welcome, #{user.fullName}
p
a.small(href="profile") Edit my profile
form(action='/logout', method='POST')
button.btn.btn-default(type="submit") Logout
else
p Welcome to the release control system , please log in to get started.
p
a.btn.btn-primary(href="/login") Login now
p
span.small Don't have an account?
span
a.small(href="/register") Register now
和 paackage.json ，

},
"description": "Release control",

请告知应修改的位置以修复错误，包括按“立即登录”按钮。
任何建议都表示赞赏，因为我不熟悉node.js和Express框架，我想实现用户管理，谢谢。

我在Stormpath工作。使用快速stormpath处理您的应用程序所需的设置很少。在npm install express-stormpath添加var stormpath = require('express-stormpath');后，您只需再做两件事：
// Tell your express app to use Stormpath
app.use(stormpath.init(app, {
// Add optional configuration settings here
expand: {
customData: true
}
}));
// Wait for Stormpath to tell you it's ready
app.on('stormpath.ready',function(){
console.log('Stormpath Ready');
});
完成这些步骤后，您将自动获得开箱即用的/ register，/ login，/ me，/ verify和/ forgot路由（以及这些路由的默认视图）。我们的快速入门将对此进行介绍，您可以在此处查看：https://docs.stormpath.com/nodejs/express/latest/setup.html
This tutorial解释了如何设置一个真正基本的快递项目，该项目有一个额外的视图，一个用于登录用户的个人资料页面。以下是直接从教程中复制/粘贴的代码。如果这对您有用，请告诉我。
server.js：
var express = require('express'); var stormpath = require('express-stormpath');
var app = express();
app.set('views', './views'); app.set('view engine', 'jade');
app.use(stormpath.init(app, { expand: {
customData: true } }));
app.get('/', stormpath.getUser, function(req, res) { res.render('home', {
title: 'Welcome' }); });
app.on('stormpath.ready',function(){ console.log('Stormpath Ready'); });
app.listen(3000);
profile.js：
var bodyParser = require('body-parser');
var cookieParser = require('cookie-parser');
var csurf = require('csurf');
var express = require('express');
var extend = require('xtend');
var forms = require('forms');
var collectFormErrors = require('express-stormpath/lib/helpers').collectFormErrors;
// Declare the schema of our form:
var profileForm = forms.create({
givenName: forms.fields.string({

}),
surname: forms.fields.string({ required: true }),
streetAddress: forms.fields.string(),
city: forms.fields.string(),
state: forms.fields.string(),

// A render function that will render our form and
// provide the values of the fields, as well
// as any situation-specific locals

// form is being POSTED and does not have errors

// find a valid token on the form

// render the form anyways, but tell them what happened
