我正在构建一个非常小的示例应用程序来练习登录页面。 我正在与:
1) Bootstrap
2) Bootswatch - 特别是日记形式
3) Font Awesome
成功设置所有组件后，如果我在 index.js 中应用以下更改，则会出现一个非常奇怪的错误负责渲染我的 localhost:5000 窗口的文件
router.get('/', (req, res) => res.send('welcome')); <-- This way works
router.get('/', (req, res) => res.render('welcome')); <-- This way throws error
app.js
const express = require('express');
const expressLayouts = require('express-ejs-layouts');
const app = express();
app.use(expressLayouts);
app.set('view engine', 'ejs');
// Routes
app.use('/', require('./routes/index'));
app.use('/users', require('./routes/users'));
const PORT = process.env.PORT || 5000;
app.listen(PORT, console.log(`Server started on port ${PORT}`));
index.js
const express = require('express');
const router = express.Router();
router.get('/', (req, res) => res.send('welcome')); // <-- This way works
router.get('/', (req, res) => res.render('welcome')); // <-- This way throws error
module.exports = router;
users.js
const express = require('express');
const router = express.Router();
// Login Page
router.get('/login', (req, res) => res.send('Login'));
// Register Page
router.get('/register', (req, res) => res.send('Register'));
module.exports = router;

错误:
Error: Failed to lookup view "layout" in views directory "/home/emanuele/Desktop/cashman-tracker-dashboard/views" at Function.render (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express/lib/application.js:580:17) at ServerResponse.render (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express/lib/response.js:1012:7) at /home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express-ejs-layouts/lib/express-layouts.js:113:20 at tryHandleCache (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/ejs/lib/ejs.js:260:5) at View.exports.renderFile [as engine] (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/ejs/lib/ejs.js:459:10) at View.render (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express/lib/view.js:135:8) at tryRender (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express/lib/application.js:640:10) at Function.render (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express/lib/application.js:592:3) at ServerResponse.render (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express/lib/response.js:1012:7) at ServerResponse.res.render (/home/emanuele/Desktop/cashman-tracker-dashboard/node_modules/express-ejs-layouts/lib/express-layouts.js:77:18)
到目前为止我所做的事情:
1) 我认为这是一个错误，因为 render方法并去检查official documentation about it但我没有发现我编写的一小部分代码有任何问题。
2) 如果更容易理解，还提供打印屏幕:
请指出解决此问题的正确方向
最佳答案
查找目录中没有名为 welcome 的 view。
当您使用 res.send('welcome') 时，express 将仅发送 welcome text 的响应，因此它看起来不会对于任何查看页面。
但另一方面，当您使用 res.render 时，它将搜索名为 welcome.ejs 的 template View 。
res.render is used to load up an ejs view file
使用 welcome.ejs 在 View 中创建一个文件并尝试。
希望这能解决问题。
