I just started working on a project that was developed by another developer (reactjs project) , however when I try to start the project I get this error in the browser console : 

Uncaught ReferenceError: Popper is not defined

The error is pointing to a specific line of course which is in the file : 

node_modules/bootstrap/dist/js/bootstrap.js

the error in the last line of the following :

    var bootstrap = (function (exports,$,Popper) {
'use strict';

$ = $ && $.hasOwnProperty('default') ? $['default'] : $;
Popper = Popper && Popper.hasOwnProperty('default') ? Popper['default'] : Popper;

 // a lot of generated code 


}({},$,Popper));

As I said earlier the error shows up pointing to the last line with the error mentioned before

Note : I have searched all other possible answers here in stack overflow but with no luck , including this answer Bootstrap 4: Uncaught ReferenceError: Popper is not defined so please it is not a duplicate

  • @AndyRay not a duplicate I've already checked that answer he used another way to implement popper and bootstrap , didn't work for me – keloa zoldik Nov 19 '17 at 01:33

The problem was not in the code , the problem was that I had an old version of nodejs and npm on my machine I thought this might help someone in the future.
