Angular 2快速启动ENOSPC错误
我正在尝试关于angularScript 2的官方5 Min Quickstart 。 我遵循所有步骤，当我运行npm start它popup我的Firefox浏览器上预期的My First Angular 2 App消息。
但是，当我检查控制台，我发现错误消息：
Error: watch node_modules/angular2/es6/dev/src/common/directives/ng_if.js ENOSPC
我不知道它是否与我之前在项目的根文件夹上运行npm install时收到的警告消息相关：
npm WARN install Couldn't install optional dependency: Unsupported npm WARN EPACKAGEJSON angular2-quickstart@1.0.0 No description npm WARN EPACKAGEJSON angular2-quickstart@1.0.0 No repository field.
有人能告诉我我的方法有什么问题吗？ 更详细的控制台输出如下所示：

我通过增加inotify观察者的数量来解决这个问题：
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
尝试使用sudo npm start
