我正在努力学习node.js。我希望能够使用vash视图引擎，但由于某些原因，我无法使其工作。我看了一个关于Pluralsight的教程，并引用了vash文档，但我一直收到同样的错误。这是我的代码
server.js:
var http = require('http');
var port = process.env.port || 1337;
var express = require("express");
var app = express();
app.set("view engine", "vash");
app.get("/", function (req, res) {
res.render("index", { title: "Express + Vash" });
});
var server = http.createServer(app);
server.listen(port);layout.vash:
<!DOCTYPE html>
<html>
<head>
<title>@model.title</title>
</head>
<body>
<div>@html.block("body")</div>
</body>
</html>index.vash
@html.extend('views/layout', function(model) {
@html.block("body", function(model) {
<h1>@model.title</h1>
<p>This id from the server</p>
})
})堆叠跑道：

提前感谢！
根据此vash问题，以下内容应该有效：
var vash = require('vash');
vash.__express = vash.renderFile;
app.set("view engine", "vash");
在index.vash中，只需使用'/layout'而不是'views/layout'。
即：
@html.extend(**'/layout'**, function(model) { ... });
