我使用Angular2Cli作为Angular 2应用程序的运行时环境。我对它的体系结构、一流的开发工具以及整体深思熟虑（因为没有更好的词）印象深刻。
然而，大约每五次保存（构建）我的服务器就会生成错误消息：
Error: Trying to add a new entry to an already existing one:
然后我必须终止这个过程并重新启动它来解决问题。
以下是全文：

The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:

我似乎只有在出现编码错误时才会遇到问题，但这并不是说编码错误和此消息之间存在1-1的对应关系——我生成的大多数编码错误都会而不是生成此消息。
一旦我收到错误，服务器似乎会进入阻止状态，无论我做什么，包括修复编码问题，都会让问题消失。只有当我循环使用服务器时，它才会消失
必须不断检查这种情况并循环服务器（大约需要6秒）来解决这个问题，这真的很乏味。
我可以发布我的代码，但我看不出代码和收到这条消息之间有任何押韵或原因，所以我认为这不会有帮助，也就是说，我认为这是环境问题，而不是编码问题。我尝试删除错误消息中列出的tmp目录，但没有成功。
我这样启动我的服务器：
vturner@vturner-virtual-machine ~/vtstuff/angular/projects/ang2-cli2 $
sudo ng serve

注意：我一直以sudo的身份运行服务器，因为我要么有权限问题，要么在某个地方读到它以sudo运行得更快（最后一个可能只在windows上适用），但我不认为以sudo身份运行与我的问题有关。
这是我的包.json:

有人能告诉我我做错了什么吗，或者我能做些什么来防止这种情况发生吗？
非常感谢。
如果您是windows用户，请在管理模式下运行您的终端。我也面临同样的问题，它对我有效：）
