错误：找不到模块'ejs' [英] Error: Cannot find module 'ejs'

问题描述

这是我的完整错误：

Error: Cannot find module 'ejs'
    at Function._resolveFilename (module.js:317:11)
    at Function._load (module.js:262:25)
    at require (module.js:346:19)
    at View.templateEngine (/Users/shamoon/local/node/lib/node_modules/express/lib/view/view.js:133:38)
    at Function.compile (/Users/shamoon/local/node/lib/node_modules/express/lib/view.js:65:17)
    at ServerResponse._render (/Users/shamoon/local/node/lib/node_modules/express/lib/view.js:414:18)
    at ServerResponse.render (/Users/shamoon/local/node/lib/node_modules/express/lib/view.js:315:17)

    at param (/Users/shamoon/local/node/lib/node_modules/express/lib/router/index.js:246:11)

我的来源代码也很简单：

My source code is also very simple:

var express = require('express');

var app = module.exports = express.createServer();

// Configuration

app.configure(function(){
  app.use(express.bodyParser());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

app.set('view engine', 'ejs');
app.set('view options', {
    layout: false
});

app.get('/', function(req, res) {
  res.render('index', {
    message : 'De groeten'
  });
});

app.listen(3000);
console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);

在我的文件夹中，我在node_modules中安装了ejs，我使用 npm安装ejs 。
所以我的问题是..什么给？我做错了什么，当我清楚地安装它时，节点找不到EJS？

In my folder, I have ejs installed in node_modules which I got using npm install ejs. so my question is.. what gives? What am I doing wrong so that node can't find EJS when I clearly have it installed?

谢谢

推荐答案

几天前我有这个完全相同的问题，无法理解。没有妥善解决问题，但这可以作为临时解决方案：

I had this exact same problem a couple of days ago and couldn't figure it out. Haven't managed to fix the problem properly but this works as a temporary fix:

上一级（app.js上方），然后执行 npm安装ejs 。它将创建一个新的node_modules文件夹，然后Express应该找到该模块。

Go up one level (above app.js) and do npm install ejs. It will create a new node_modules folder and Express should find the module then.
