我正在试用官方
5 Min Quickstart关于角度2的Typescript.我遵循所有步骤,当我运行npm开始它确实在我的Firefox浏览器弹出预期的我的第一个Angular 2应用程序消息.
但是,当我检查控制台时,我发现错误消息：
Error: watch node_modules/angular2/es6/dev/src/common/directives/ng_if.js ENOSPC
当我在项目的根文件夹下运行npm安装时,我不知道是否与我之前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.
有人可以告诉我我的做法有什么问题吗？更详细的控制台输出如下所示：

解决方法
我通过增加知识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
