Question

我正在尝试创建第一款游戏的步骤：

我只是按照以下步骤操作：

“一旦安装了node.js，就可以在项目目录中安装基本的voxel.js npm包，然后安装基本的纹理包。在项目目录中创建一个名为package.json的文件，并将其内容提供给它：”

{
  "name": "mygamename",
  "version": "0.0.1",
  "dependencies": {
    "voxel-hello-world": "0.6.0"
  }
}

“现在您可以告诉节点安装依赖项：”

$ npm install

“下一步，创建mygame.js并将以下代码放入其中：”

var createGame = require('voxel-hello-world')
var game = createGame()

“然后使用browserify构建游戏：”

$ npm install browserify -g
$ browserify mygame.js -o builtgame.js

“将builtgame.js加载到网页中：”

<!doctype html>
<html>
  <body>
    <script src="builtgame.js"></script>
  </body>
</html>

错误：

builtgame.js:49790 Uncaught TypeError: Cannot read property 'appendChild' of null
    at Game.addStats (builtgame.js:49790)
    at Game.initializeRendering (builtgame.js:50033)
    at new Game (builtgame.js:49481)
    at Game (builtgame.js:49399)
    at module.exports (builtgame.js:50538)
    at Object.31.voxel-hello-world (builtgame.js:6180)
    at o (builtgame.js:1)
    at r (builtgame.js:1)
    at builtgame.js:1

如何解决这种情况并成功执行appendChild？

为什么使用已安装的软件包voxel.js不能向我显示已安装在nodejs中的hello world软件包？
