Using Nunjucks with Express 4

Question

I am trying to use Nunjucks as a template engine from Express. I did this:

var express = require('express');
var nunjucks = require('nunjucks');
var path = require('path');
var bodyParser = require('body-parser');
var load = require('express-load');
var fs = require("fs");

var app = express();
app.set('views', path.join(__dirname, 'views'));

var env = nunjucks.configure(app.get('views'), {
    autoescape: true,
    express:    app 
});

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

But above code gives this error:

Template render error: compileExtends: cannot extend multiple times
   at Error.exports.TemplateError (C:\my\nodejs\projects\\node_modules\nunjucks\src\lib.js:49:19)

   at Obj.extend.compile (C:\my\nodejs\projects\\node_modules\nunjucks\src\environment.js:403:18) 

Please tell me how to fix this ?

I just setup nunjucks using the default way:

const express = require('express');
const nunjucks = require('nunjucks');

const app = express();
app.engine('html', nunjucks.render);
app.set('view engine','html');
app.set('views', globals.viewsDirectory);

"express": "4.16.4", "nunjucks": "^3.2.3",
