Question

我正在使用Angular2 Cli作为Angular 2应用程序的运行时环境。我对它的体系结构，最好的开发工具以及整体精心设计的（缺乏更好的词）给我留下了深刻的印象。

但是，大约每五次保存（构建）我的服务器都会生成错误消息：

Error: Trying to add a new entry to an already existing one:

然后我必须终止该过程并重新启动它以解决问题。

以下是全文：

The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:

当出现编码错误时，我似乎只能解决问题，但这并不是说编码错误与此消息之间存在1-1对应关系 - 我生成的大多数编码错误都会不生成这条消息。

一旦我收到错误，服务器似乎进入阻塞状态，无论我做什么，包括修复编码问题，都会使问题消失。它只会在我循环服务器时消失必须继续检查这种情况并骑自行车服务器（需要大约6秒）来解决这个问题变得非常繁琐。

我可以发布我的代码，但我没有看到代码和获取此消息之间的任何押韵或原因，所以我认为这不会有所帮助，即我认为这是一个环境问题，而不是编码问题。我已经尝试删除错误消息中列出的tmp目录，但这不起作用。

我这样启动我的服务器：

vturner@vturner-virtual-machine ~/vtstuff/angular/projects/ang2-cli2 $ 
sudo ng serve

注意：我一直在以sudo的身份运行服务器，因为我要么遇到权限问题，要么我在某个地方读到它运行速度更快的sudo（最后一个可能只在Windows上运行），但我不认为以sudo身份运行与我的问题有关。

这是我的package.json：

}

有谁能告诉我我做错了什么，或者我能做些什么来防止这种情况？

非常感谢。

如果您是Windows用户，请在管理模式下运行终端。我遇到了同样的问题，它对我有用:)
