无法使用angularjs和gulp实例化模块应用程序（npm start）

Question

我有一个angularjs和gulp的问题。当我运行npm run production时，一切都被完美地编译。也可以在Firefox中打开index.html，并且Web应用程序可以正常运行。但是，如果我使用npm start，我总会收到此错误：

  

错误：[$ injector：modulerr]由于以下原因无法实例化模块应用：
  [$ injector：nomod]模块'app'不可用！你要么拼错了   模块名称或忘记加载它。如果注册模块，请确保将依赖项指定为第二个参数   http://errors.angularjs.org/1.4.7/ $注射器/ NOMOD？P0 =应用

这告诉我该应用程序尚未找到。但是，代码已针对gulp和angularjs（依赖注入）进行了适当调整。因此它在Firefox中运行而不会抛出错误。

你知道这个错误的原因是什么吗？如何让npm start正常运行？

这就是package.json
