node.js - 如何更改 express 的 Handlebars 延长件？

Question

我是 node.js 的新手，我想使用 handlebars 模板引擎，但使用较短的扩展名 hbs。

这是原始代码(source):

var handlebars = require('express3-handlebars')
.create({ defaultLayout: 'main' });
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'handlebars');

它在带有 handlebars 扩展名的模板上运行良好，但我将其更改为:

var handlebars = require('express3-handlebars')
.create({ defaultLayout: 'main' });
app.engine('hbs', handlebars.engine);
app.set('view engine', 'hbs');

并将所有模板扩展更改为hbs。但是，现在我收到此错误:

Error: ENOENT: no such file or directory, open '/path/to/node/myproject/views/layouts/main.handlebars'
   at Error (native)

我也试过

var handlebars = require('express3-handlebars')
.create({ defaultLayout: 'main' , extname : '.hbs'});
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'handlebars');

根据回答here ,

但我的结果是:

Error: Failed to lookup view "500" in views directory "/path/to/myproject/views"

   at trim_prefix (/path/to/myproject/node_modules/express/lib/router/index.js:310:13)

我也尝试了其他方法，但都没有用，所以想知道我该如何解决这个问题？

这成功了:

exphbs = require('express3-handlebars'),
app.engine('hbs', exphbs({defaultLayout: 'main', extname: '.hbs'}));
app.set('view engine', 'hbs');
