错误:ENOENT:Express-Handlebars中没有这样的文件或目录

问题描述

我正在使用express-handlebars在NodeJS中加载动态内容

I am using express-handlebars to load dynamic content in NodeJS

内部app.js

const express = require("express");
const bodyParser = require("body-parser");
const path = require("path");
const pp = require("./util/path.js");
const adminRoutes = require("./routes/admin");
const shopRoutes = require("./routes/shop");
const expressHbs = require("express-handlebars");
const app = express();

app.engine("hbs",expressHbs());
app.set("view engine", "hbs");
app.set("views", "views");

app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, "public")));

app.use("/admin", adminRoutes.routes);
app.use(shopRoutes);

app.use((req, res, next) => {
  res.status(404).render("404", { pageTitle: "Page Not Found" });
});
app.listen(3001, "localhost", () => console.log("Listening on 3001 PORT"));

expressHbs()函数没有参数时，将显示以下错误

When expressHbs() function has no param it shows the following error

当我将选项对象传递给它时:

And when i pass an option object to it:

app.engine(
  "hbs",
  expressHbs({
    extname: "hbs",
    layoutsDir: path.join(__dirname, "views")
  })
);

它显示:

我一直在寻找解决方案，但没有结果，实际上，我正在按照教程进行操作，与老师的操作相同，但是出现错误.

I've searched for a solution but i got no result , Actually i am following a tutorial and i have done the same as teacher did but i got an error.

我最近尝试过的事情是添加 defaultLayout 属性，它可以工作并加载默认值，但是当我将网址更改为另一页时，它总是加载我设置为默认值的同一页面

Lastly thing that i have tried is adding defaultLayout property and it works and load the default but when i change the url to another page it always load the same page which i set as default

这是项目文件夹及其所有内容

Here is project folder and all its contents

推荐答案

实际上express-handlebars有点烦人，但解决了以下问题:

Actually it's a bit annoying problem with express-handlebars but got it solved as following:

• 我必须创建一个不是Routes之一的独立文件，并将其名称分配给defaultLayout
• 我必须将路径设置为views/layouts/
• 我必须为已定义的扩展名定义extname

• I had to create a standalone file which's not one of Routes and assign its name to defaultLayout
• I had to set the path to views/layouts/
• I had to to define extname to the extension i had defined

app.engine(
  "hbs",
  expressHbs({
    extname: "hbs",
    defaultLayout: "main-layout",
    layoutsDir: "views/layouts/"
  })
);
