linux - Angular2 未处理的 'error' 事件

Question

我在 ubuntu 15 上用 ts 构建了一个 angular 2 的仪表板。但是，

在我的输入和 Node 模块所在的 retail-dashboard 文件夹中使用 npm start 进行编译时，我遇到了 npm 错误。它将打开一个网页，但它没有加载任何错误 conn refused

我现在处于停顿状态，不知道该做什么

我遇到了同样的问题，并通过发出以下命令使其正常工作:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

如解释here ，系统对用户可以观看的文件数量有限制。显然你可以用完 watch 。此命令增加了用户可以拥有的最大 watch 数量。

我首先找到了解决方案 here ，然后跟踪到 stackoverflow 帖子。

希望对您有所帮助!
