Three.js - 未捕获TypeError：undefined不是函数

Question

I'm getting the Uncaught TypeError: undefined is not a function while using Three.js. The error is being shown for the line where I'm creating a THREE.PerspectiveCamera . The script is

window.requestAnimFrame = (function(callback){
        return window.requestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.oRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        function(callback){
            window.setTimeout(callback, 1000 / 60);
        };
    })();

    function animate(lastTime, angularSpeed, three){
        // update
        var date = new Date();
        var time = date.getTime();
        lastTime = time;

        // render
        three.renderer.render(three.scene, three.camera);

        // request new frame
        requestAnimFrame(function(){
            animate(lastTime, angularSpeed, three);
        });
    }

    $(window).bind('load',function(){
        var angularSpeed = 0.2; // revolutions per second
        var lastTime = 0;
        $container = $("#container");
        var renderer = new THREE.WebGLRenderer();
        renderer.setSize(window.innerWidth, window.innerHeight);
        $container.append(renderer.domElement);

        // camera - Uncaught Type Error on the below line
        var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 1000);
        camera.position.y = -450;
        camera.position.z = 400;
        camera.rotation.x = 45 * (Math.PI / 180);

        // scene
        var scene = new THREE.Scene();

        var material = new THREE.LineBasicMaterial({
                            color: 0x0000ff,
                        });
        var geometry = new THREE.Geometry();
        for(var i=0;i<100;i++){
            geometry.vertices.push(new THREE.Vector3(i-100,i-100,i-100));
            geometry.vertices.push(new THREE.Vector3(i+100,i+100,i+100));
            var line = new Three.Line(geometry,material);
            scene.add(line);
            geometry=new THREE.Geometry();
        }


        // create wrapper object that contains three.js objects
        var three = {
            renderer: renderer,
            camera: camera,
            scene: scene,
        };

        animate(lastTime, angularSpeed, three);
    });

Is this because the way I'm declaring the camera is wrong? I checked the three.js documentation and the example give there is basically the same. So I'm stuck on what to do.

UPDATE: I was using a local copy of Three.js when I encountered the last error. I switched it with the link http://www.html5canvastutorials.com/libraries/Three.js . Now, the PerspectiveCamera error is gone, but it produces a new error inside the Three.js script. The error is Uncaught TypeError: Cannot read property 'x' of undefined on line 337 of the Three.js script

Thanks.

The problem with the local copy is you used the unbuilt Three.js file (that would be src/Three.js). The one you want is either build/three.js or build/three.min.js. I copied that into my project, and changed the reference to it in the script tag's src attribute, and it all started working.

In short:
