【问题描述】：
我使用Angular2 Cli 作为我的 Angular 2 应用程序的运行时环境。它的架构、一流的开发工具和整体深思熟虑（因为没有更好的词）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:
然后我必须终止该进程并重新启动它以解决问题。
这是全文：
file changed app/vtClass.ts
The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:

我似乎只在出现编码错误时才遇到问题，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不生成这条消息。
一旦我收到错误，服务器似乎会进入一个阻塞状态，无论我做什么，包括修复编码问题，都会让问题消失。只有在我循环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来解决这个问题，这变得非常乏味，这需要大约 6 秒。
我可以发布我的代码，但我没有看到代码与收到此消息之间的任何押韵或原因，所以我认为这不会有帮助，即我认为这是一个环境问题而不是编码问题。我已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
Could not start watchman; falling back to NodeWatcher for file system events.

注意：我一直以 sudo 运行服务器，因为我要么遇到权限问题，要么在某处读到它以 sudo 运行得更快（最后一个可能只在 Windows 上是真的），但我不认为以 sudo 运行与我的问题有关。
这是我的 package.json：

谁能告诉我我做错了什么，或者我可以做些什么来防止这种情况发生？
非常感谢。

我注释掉了 node_modules/angular-cli/lib/broccoli/broccili-typescript.js 中的错误行：
_addNewFileEntry(entry) { const p = path.join(this.inputPaths[0], entry.relativePath); if (this._fileRegistry[p]) { //vt add console.log("vt.broccoli-typescript.js: intercepting dupicate entry error"); //vt end //vtthrow new Error('Trying to add a new entry to an already existing one: ' + p); }但现在我得到了Error: EEXIST: file already exists我认为这可能是一个库问题。见github.com/ember-cli/ember-cli/issues/3413 -
我在使用 Angular 2 CLI 时遇到了完全相同的问题。每次都必须杀死并重新启动服务器非常乏味。您是否将此作为问题提交到 CLI 的 Github 上？
-
我在 angular-cli repo 上找到了类似的 open issue。我添加了“我也是”评论以及我的详细信息。开票的人指出，这种情况只有在您修复以前标记的错误时才会发生。我能够验证这是为我生成条件的机制。
-
我在ticket 中发布了一个解决方法（小的源代码更改）。只是临时修复，直到开发人员能够提出实际修复。
