Bootstrap: Uncaught TypeError: Cannot read property 'fn' of undefined

Question

I am trying to make an Electron application with Bootstrap. I get this error message:

Uncaught TypeError: Cannot read property \'fn\' of undefined
at setTransit         


        

Answer 1

I found a way to solve the problem.

I added a script in the index.html:

and this is the content of script.js:

window.$ = window.jQuery = require('jquery'); // not sure if you need this at all
window.Bootstrap = require('bootstrap');

and we can remove these lines from index.html to avoid double import:
