  2. - Edit package.json to use mocha for testing. When test is invoked, we just want to run - mocha and specify a verbose reporter. By default this will run anything in test/ - (not having directory test/ can run into npm ERR!, create it by mkdir test) + 编辑package.json来使用mocha进行测试。当调用测试的时候，我们只想运行mocha并且生成一份详细的报告。 + 默认情况下这会运行 test/ 中的任何东西。 + （如果项目中没有 test/ 目录的话，会导致npm报错。你可以通过mkdir test来创建这个目录） "test": "mocha --reporter list"

Dealing with dependencies

处理依赖

- If you're already using something clever like require.js or browserify, skip this part. + 如果你已经在使用require.js或者browserify之类的便捷工具，就跳过这个部分。

- Typically a three.js project is going to run in the browser. Module loading is hence done by - the browser executing a bunch of script tags. Your individual files don't have to worry - about dependencies. In a nodejs context however, there is no index.html binding everything - together, so you have to be explicit. + 一般来说，一个three.js项目将在浏览器中运行，浏览器会通过执行一系列script标签来加载模块。 + 你自己的文件不用考虑依赖的问题。然而在nodejs环境中，没有一个关联所有文件的index.html，所以你需要显式地加载。

- If you're exporting a module that depends on other files, you're going to have to tell node to load them. - Here is one approach: + 如果你要导出的模块还依赖其他文件，你需要告诉node去加载它们。下面是一种方式：

  1. - At the start of your module, check to see if you're in a nodejs environment. + 在你的模块顶部，检查是否处于nodejs环境中。
  2. - If so, explicitly declare your dependencies. + 如果是，那就显式地声明你的依赖。
  3. - If not, you're probably in a browser so you don't need to do anything else. + 如果不是，你多半处于浏览器环境中。这时候你不需要做任何多余操作。
