Question

出于某种原因，每次我尝试使用{{#iff}时，我都会收到此错误这不是我的页面作为把手吗？我是否正确使用了{{#iff}}语句？

我的控制台打印出来：

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

这是我的把手（login.hbs）：

<h1><span class="fa fa-sign-in"></span> Login</h1>

{{#iff message.length '>' 0}}
    <div class="alert alert-danger">{{message}}</div>
{{/iff}}

这是我的server.js

var express  = require('express');
var app      = express();
var port     = process.env.PORT || 8080;
var mongoose = require('mongoose');
var passport = require('passport');
var flash    = require('connect-flash');
const hbs = require('hbs');
var morgan       = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser   = require('body-parser');
var session      = require('express-session');

var configDB = require('./config/database.js');


mongoose.connect(configDB.url); // connect to our database

require('./config/passport')(passport); // pass passport for configuration

// set up our express application
app.use(morgan('dev')); // log every request to the console
app.use(cookieParser()); // read cookies (needed for auth)
app.use(bodyParser.json()); // get information from html forms
app.use(bodyParser.urlencoded({ extended: true }));

app.set('view engine', 'hbs'); // set up hbs for templating

// required for passport
app.use(session({
    secret: 'ilovescotchscotchyscotchscotch', // session secret
    resave: true,
    saveUninitialized: true
}));
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session


require('./app/routes.js')(app, passport); // load our routes and pass in our app and fully configured passport


app.listen(port);
console.log('The magic happens on port ' + port);

在routes.js中：

  app.get('/login', function(req, res) {
        res.render('login.hbs', { message: req.flash('loginMessage') });
    });

错误：缺少助手：＆＃34; iff＆＃34;
