为什么 express 无法在 views 文件夹中查找 ejs 文件？

Question

开始学习 NodeJS 和 Express。

// express framework 
var express  = require("express");
var app = express();

app.get("/", (req,res) =>
{
    res.render("home.ejs");
})

//port listening 
app.listen(3000, ()=>
    [
        console.log("Server listening at 3000")
    ])

views 文件夹与代码位于同一文件夹中，并且包含文件 home.ejs。

我收到以下错误

Error: Failed to lookup view "home.ejs" in views directory "/Users/username/Desktop/Programming/JavaScript/views"
    at Function.render (/Users/username/node_modules/express/lib/application.js:580:17)

Answer 1

我明白了。有人建议添加。

app.set('view engine', 'ejs')

这本身不起作用，但后来我环顾四周，发现我还需要添加以下行。

app.set('views', path.join(__dirname, 'views'));

我正在学习的教程没有任何这段代码，所以我有点困惑。

感谢您的帮助。
