javascript - Meteor 应用程序可能在 Chrome 更新后无法在 Chrome 中运行

Question

我有一个用 Meteor 构建的应用程序。我在本地运行它，它也部署在服务器上。我刚刚发现该应用程序不再在 Chrome 上运行。我不确定，但可能唯一的区别是我的 Chrome 今天获得了更新。该应用程序在 Firefox 和 IE Edge 以及较旧的 IE 上运行良好。我查看了控制台并发现了这些错误:

Exception in callback of async function: Error: Handler with name 'hookWithOptions' already exists.

上面的错误是针对本地主机上的应用程序。

部署在服务器上的，在2、3次commit之后出现了这些错误:

Exception in callback of async function: Error: Handler with name 'u' already exists.

我从没想过浏览器更新可能会像那样破坏您的应用程序。有谁知道出了什么问题？如果您想查看，该应用程序的链接是:http://mynotes.work/

我当前的 Chrome 版本是这样的:51.0.2704.84 m

根据这个线程 https://forums.meteor.com/t/solved-error-handler-with-name-u-already-exists/23910/12更新 irron:middleware-stack 有帮助。

meteor update iron:middleware-stack 应该可以解决这个问题。
