javascript - Node js中的Heroku html子页面

Question

你好，我刚接触编程，我开始在 heroku 中制作我的简单作品集 问题是子页面我不知道如何将新的子页面添加到我的投资组合我总是得到 Cannot GET/frontend.ejs

链接到我的投资组合: http://poninsky.herokuapp.com

我对 node js 了解不多

这是来自 index.js 的代码，我从 heroku 获得了添加子页面所需的内容:

var express = require('express');
var app = express();

app.set('port', (process.env.PORT || 5000));

app.use(express.static(__dirname + '/public'));

// views is directory for all template files
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');

app.get('/', function(request, response) {
response.render('pages/index');
});
app.get('/frontend', function(request, response) {
response.render('pages/frontend');
});

app.listen(app.get('port'), function() {
console.log('Node app is running on port', app.get('port'));
});

谢谢解答!

运行后我得到这个:

module.js:471
throw err;
^

这里可能有几个问题，第一个也是最重要的是它看起来不像你的依赖项已经安装。您的元素是否有一个 package.json 列出了所有依赖项，例如 Express？ Heroku 安装包 list 那部分中列出的任何内容；确保还指定您的引擎(即 Node 和版本)，以便 Heroku 知道要使用的 Node 版本。

当您访问您的端点时，也不要将 .ejs 放在它们的末尾。 EJS 仅用作 View 引擎并编译为 HTML。
