Express js render : TypeError: this.engine is not a function [duplicate]

Question

I am getting TypeError: this.engine is not a function. I don`t know why I am getting this error. Can anyone please help me to solve this issue.

My server file:

var express = require('express');

var path = require('path');

var app = express();

//configure app
app.set('view engine', 'html');
app.set('views', path.join(__dirname, 'views'));

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


app.listen(3000, function() {
    console.log('Ready on port 1337');
});

And my HTML file:

<!DOCTYPE html>
<html>

<head>

</head>

<body>
    <div>Hello Express</div>
</body>

</html>

I get the error

My package.json:

{
    "name": "app",
    "version": "1.0.0",
    "main": "index.html",
    "directories": {
        "test": "test"
    },
    "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1"
    },
    "author": "mehadi",
    "license": "UNLICENSED",
    "dependencies": {
        "express": "4.13.0",
        "html": "^1.0.0"
    },
    "repository": {
        "type": "git",
        "url": "(github.com/mehadi07/Random.git)"
    },
    "devDependencies": {},
    "description": ""
}

I installed the html engine via

npm install --save html

What's your package.json? Where are you registering this 'html' view engine, and what engine are you registering? — T.J. Crowder
What template engine you're trying to use ? I don't recognize html-template engine. Have you installed the engine (with npm) ? Please RTFM: expressjs.com/en/guide/using-template-engines.html — user272735

The html package you've installed is unrelated to Express. So it's not surprising that if you tell Express to use it, it fails.

If you're looking to serve static HTML files, see this question's answers, and the Express documentation. The simplest way is just

app.use(express.static('views'));
