requireJS “Uncaught TypeError: undefined is not a function”

Question

I have been using requirejs on couple projects, and today is the first time I got this problem and not sure how to fix it. I am using requirejs and tyepscript, I can't really tell what's wrong here. Can someone take a look?

Here is my main.ts:

///<reference path="../lib/require/requirejs.d.ts"/>
///<reference path="TestClass.ts"/>
require.config(
    {
        baseUrl: 'js',
        paths: {
            puremvc: 'lib/puremvc/puremvc_standard_1.0_min'
        }
    }
);
require(
    [
        'puremvc',
        'sim/TestClass'
    ],
    function (TestClass ) {
        var test = new TestClass();
        test.logMsg("WHO AM I");
    }
);

and this is my TestClass.ts

class TestClass{
    constructor(){
        console.log ("TestClass constructor")
    }
   public logMsg(msg:string){
        console.log ("TestClass.log(): " + msg);
    }
}
export = TestClass;

and my sim.html looks like this one

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Simulation Tester</title>
<script src="js/lib/puremvc/puremvc_standard_1.0_min.js"></script>
<script data-main="js/sim/main.js" src="js/lib/require/require.js" ></script>
</head>
<body >
</body>
</html>

And this is my folder structure:

- root 
    - sim.html
    - js
        - lib
            - require (containt requirejs)
        - sim
            - main.ts
            - TestClass.ts

Any idea?

Are you loading puremvc through the script tag, or through require.js? I don't think you want to do both.

Over here:

require(
    [
        'puremvc',
        'sim/TestClass'
    ],
    function (TestClass ) {
        var test = new TestClass();
        test.logMsg("WHO AM I");
    }
);

The callback function gets the modules in the same order you listed them. So the 'TestClass' parameter is being supplied the value from the 'puremvc' module. You probably want function(puremvc, TestClass) instead here.

That's it. I remove puremvc script tag from HTML and change the function(TestClass) to function (puremvc, TestClass) Thank you so much. I guess I've been doing it all wrong a while but now today is the first time I got this error. Thanks again.
