Here is my complete error:
Error: Cannot find module 'ejs'

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);
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?
Thanks
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. Hope it helps!!
EJS simply stands for Embedded Javascript. It is a simple templating language/engine that lets its user generate HTML with plain javascript. EJS is mostly useful whenever you have to output HTML with a lot of javascript.
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:
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.
(npm install express
while in the project's root directory)
Your project depends on both express
and ejs
, so you should list them both as dependencies in your package.json
.
That way when you run npm install
in you project directory, it'll install both express
and ejs
, so that var express = require('express')
will be the local installation of express (which knows about the ejs
module that you installed locally) rather than the global one, which doesn't.
In general it's a good idea to explicitly list all dependencies in your package.json
even though some of them might already be globally installed, so you don't have these types of issues.
I my case, I just added ejs manually in package.json:
{
"name": "myApp"
"dependencies": {
"express": "^4.12.2",
"ejs": "^1.0.0"
}
}
And run npm install (may be you need run it with sudo) Please note, that ejs looks views directory by default
Way back when the same issue happened with me.
Dependency was there for ejs in JSON file, tried installing it locally and globally but did not work.
Then what I did was manually adding the module by:
app.set('view engine','ejs');
app.engine('ejs', require('ejs').__express);
Then it works.
I had the same issue. Once I set environment variable NODE_PATH to the location of my modules (/usr/local/node-v0.8.4/node_modules in my case) the problem went away. P.S. NODE_PATH accepts a colon separated list of directories if you need to specify more than one.
I installed ejs
using command npm install ejs
in express directory level and this solved my problem.
i have install express using steps mention in express guide http://expressjs.com/guide.html
Install it locally rather installing it globally. Then your project may be run on any machine without any error.I think its better.
npm install express --save
npm install ejs --save
After you've installed Express V x.x.x You need to choose an template view-engine. There are many really easy to learn. My personal go-to is EJS.
Other really great and easy to learn could be:
To install EJS (And fix your error) Run in root of your project:
npm install ejs
Or if you're using Yarn:
yarn add ejs
Next you'll need to require the module, so open up your file where you require express (usually app.js or server.js)
add below var express = require('express');
var ejs = require('ejs');
i had the same problem. So i did the following and it worked for me.
solution:
npm install ejs --save
npm install express --save
by doing so it creates the required dependencies in the package.json file
I had this problem. I debugged using node-inspector and saw that from the node_modules folder where the express source files were, ejs was not installed. So I installed it there and it worked.
npm install -g ejs
didn't put it where I expected it to despite NODE_PATH being set to the same node_modules folder. Prob doing it wrong, just started with node.
I installed both: express and ejs with the option --save:
npm install ejs --save npm install express --save
This way express and ejs are dependecies package.json file.
Reinstalling npm, express and ejs fixed my problem
This one worked for me,
after that, the error was fixed.
STEP 1
See npm ls | grep ejs
at root level of your project to check if you have already added ejs
dependency
to your project.
If not, add it as dependencies
to your project. (I prefer adding dependency to package.json
instead of npm install
ing the module.)
eg.
{
"name": "musicpedia",
"version": "0.0.0",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"body-parser": "~1.15.1",
"cookie-parser": "~1.4.3",
"debug": "~2.2.0",
"express": "~4.13.4",
"jade": "~1.11.0",
"ejs": "^1.0.0",
"morgan": "~1.7.0",
"serve-favicon": "~2.3.0"
}
}
STEP 2 download the dependencies
npm install
STEP 3 check ejs module
$ npm ls | grep ejs
[email protected] /Users/prayagupd/nodejs-fkers/musicpedia
├── [email protected]
Add dependency in package.json
and then run npm install
{
...
...
"dependencies": {
"express": "*",
"ejs": "*",
}
}
I think ejs template engine is not properly installed on your machine. You just install the template engine using npm
npm install ejs --save
then include the following code in app.js
app.set('view engine', 'ejs')
I have the same issue it resolve after installing the express in my project directory. previously i install it in global scope with -g option with npm install command.
In my case there was no silly syntax error, but same error arised. I had installed ejs and ejs-mate globally. I installed it locally and found my error resolved.
