Mismatched anonymous define() module

I'm getting this error when I browse my webapp for the first time (usually in a browser with disabled cache).

Error: Mismatched anonymous define() module: function (require) {

HTML:

<html>
   .
   .
   .
   <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
   <script> var require = { urlArgs: "v=0.4.1.32" }; </script>
   <script data-main="assets/js/main" src="assets/js/libs/require.js"></script>
   <script src="assets/js/ace/ace.js?v=0.4.1.32"></script>
   </body>
</html>

JS:

$(function () {
    define(function (require) {
        // do something
    });
});

Anyone know exactly what this error means and why its happening?

source file, a short discussion about it in the github issues page

Solution 1:

Like AlienWebguy said, per the docs, require.js can blow up if

You have an anonymous define ("modules that call define() with no string ID") in its own script tag (I assume actually they mean anywhere in global scope)
You have modules that have conflicting names
You use loader plugins or anonymous modules but don't use require.js's optimizer to bundle them

I had this problem while including bundles built with browserify alongside require.js modules. The solution was to either:

A. load the non-require.js standalone bundles in script tags before require.js is loaded, or

B. load them using require.js (instead of a script tag)

Solution 2:

In getting started with require.js I ran into the issue and as a beginner the docs may as well been written in greek.

The issue I ran into was that most of the beginner examples use "anonymous defines" when you should be using a "string id".

anonymous defines

define(function() {
        return { helloWorld: function() { console.log('hello world!') } };
 })
    
  
define(function() {
        return { helloWorld2: function() { console.log('hello world again!') } };
 })

define with string id

define('moduleOne',function() {
    return { helloWorld: function() { console.log('hello world!') } };
})

 define('moduleTwo', function() {
      return { helloWorld2: function() { console.log('hello world again!') } };
})

When you use define with a string id then you will avoid this error when you try to use the modules like so:

require([ "moduleOne", "moduleTwo" ], function(moduleOne, moduleTwo) {
    moduleOne.helloWorld();
    moduleTwo.helloWorld2();
});
