both jQuery and $ is not a function

I already imported 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

under the head section. But still I got,

RelatedObjectLookups.js:142 Uncaught TypeError: $ is not a function
    at RelatedObjectLookups.js:142
    at RelatedObjectLookups.js:175
(anonymous) @ RelatedObjectLookups.js:142
(anonymous) @ RelatedObjectLookups.js:175
(index):177 Uncaught TypeError: $ is not a function
    at (index):177

Relavant html looks like,

<script>

$( document ).ready(function() { // line no 177

Removing the script tags above {{form.media}} won't throw any error related to jquery but it misses the widget functionality. I need that script tags but I don't want Jquery to return $ is not a function. I have tried adding $.noconflict, jQuery(document).ready but nothing works.

I’m pretty sure your whole problem is that the very end of your RelatedObjectsLookups.js JS file says django.jQuery, which doesn’t exist (or at least, the googleapis jQuery file you’re loading in isn’t going to define that). Change it to window.jQuery and things should work for you.

EDIT based on your reply

Since you can’t change the line that says django.jQuery, then let’s define that.

Right after you include your jQuery file, add the following tag.

<script>
  django = django || {};
  django.jQuery = django.jQuery || jQuery;
</script>

This will set django.jQuery to jQuery (which is included by your googleapis file), if it’s not been set yet. Now it will exist for your later scripts to use.
