Answer 1

kindly ensure that your dependencies in your package.json files are up to date. Try reinstalling them one at a time after also ensuring that your NPM is the latest version (up-to-date). It worked for me. I advise you to run npm install for the packages(thats what worked in my own case after it refused to work because I added the dependencies manually).

Answer 2

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:

• Handlebars
• PUG (Former Jade)

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 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.

Answer 4

In my case it was a stupid mistake- it was a typo in the middleware. I wrote app.set('view engine', 'ejs.'); the dot caused the error. I installed ejs and express locally

Answer 5

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.

Answer 6

Ensure all dependencies are installed. npm install

I was making a quick app for myself and I had forgotten to add express. Threw the above error.
