快速渲染html作为视图引擎需要给出回调函数的错误

Question

我正在使用html作为引擎创建一个新的快速项目，它需要hbs。

以下是引擎设置：

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hbs');
app.engine('html', require('hbs').renderFile);
app.use(express.static(path.join(__dirname, '/views')));

我收到错误：

  

错误需要回调功能

以下是它的屏幕截图：

这是我的完整app.js脚本：

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var nodemon = require('nodemon');
var consolidate = require('consolidate');
var index = require('./routes/index');
var users = require('./routes/users');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hbs');
app.engine('html', require('hbs').renderFile);
app.use(express.static(path.join(__dirname, '/views')));
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', index);
app.use('/users', users);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

这是我的npm版本：

5.5.1

The documentation说使用app.engine('html', require('hbs').__express);
