Question

当我使用npm start启动服务器，然后访问位于localhost：3000的页面时，出现以下错误：

Error: Cannot find module 'ejs'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:587:15)
    at Function.Module._load (internal/modules/cjs/loader.js:513:25)

我使用-g和--dev安装了ejs，但这些都不起作用。我还添加了这行代码app.set（'views'，'views'）;在app.set（'view engine'，'ejs'）;

下

这是主要的js文件：

const path = require('path');
const express = require('express');
const bodyParser = require('body-parser');

const app = express();

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

const adminData = require('./routes/admin');
const shopRoutes = require('./routes/shop');


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

app.use('/admin', adminData.routes);
app.use(shopRoutes);

app.use((req, res, next) => {
    res.status(404).render('404', {pageTitle: 'Page Not Found!'});
});

app.listen(3000);

这是我的package.json文件：

{
  "name": "practica-express",
  "version": "1.0.0",
  "description": "",
  "main": "express.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon express.js"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "nodemon": "^1.19.0"
  },
  "dependencies": {
    "body-parser": "^1.19.0",
    "ejs": "^2.6.1",
    "express-handlebars": "^3.0.2",
    "pug": "^2.0.3"
  }
}

查看模板如何不获取ejs引擎：

为什么Express无法找到模块ejs？
