DataTables: Uncaught TypeError: Cannot read property 'defaults' of undefined

I got the same error, I'm using laravel 5.4 with webpack, here package.json before:

{
  ...
  ...
  "devDependencies": {
    "jquery": "^1.12.4",
    ...
    ...
  },
  "dependencies": {
    "datatables.net": "^2.1.1",
    ...
    ...
  }
}

I had to move jquery and datatables.net npm packages under one of these "dependencies": {} or "devDependencies": {} in package.json and the error disappeared, after:

{
  ...
  ...
  "devDependencies": {
    "jquery": "^1.12.4",
    "datatables.net": "^2.1.1",
    ...
    ...
  }
}

I hope that helps!

Add Defer to the end of your Script tag, it worked for me (;

Everything needs to be loaded in the correct order (:

The problem is that dataTable is not defined at the point you are calling this method.

Ensure that you are loading the .js files in the correct order:

<script src="/Scripts/jquery.dataTables.js"></script>
<script src="/Scripts/dataTables.bootstrap.js"></script>
