为什么express无法在views文件夹中查找ejs文件？

Question

开始学习NodeJS并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")    ])视图文件夹位于代码的同一文件夹中，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)    at ServerResponse.render (/Users/username/node_modules/express/lib/response.js:1012:7)    at /Users/username/Desktop/Programming/JavaScript/practice/app.js:8:9    at Layer.handle [as handle_request] (/Users/username/node_modules/express/lib/router/layer.js:95:5)    at next (/Users/username/node_modules/express/lib/router/route.js:137:13)    at Route.dispatch (/Users/username/node_modules/express/lib/router/route.js:112:3)    at Layer.handle [as handle_request] (/Users/username/node_modules/express/lib/router/layer.js:95:5)    at /Users/username/node_modules/express/lib/router/index.js:281:22    at Function.process_params (/Users/username/node_modules/express/lib/router/index.js:335:12)    at next (/Users/username/node_modules/express/lib/router/index.js:275:10

Answer 1

我得到了它。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'));

我遵循的教程没有任何此类代码，所以我有点困惑。

谢谢您的帮助。
