控制台错误:ng.probe 不是函数 [英] Error in console: ng.probe is not a function

问题描述

昨天我将 Angular CLI 和核心更新到 8.0.0v.之后，我成功初始化了一个新应用程序并运行了它.在 localhost:4200 上构建并提供应用程序后，我打开控制台，出现错误:

Yesterday I updated Angular CLI and core to 8.0.0v. After that I successfully initialized a new app and ran it. Once the app was built and served on localhost:4200 I opened the console and there was an error:

ng.probe 不是函数

ng.probe is not a function

我试图研究这个问题，但没有相关信息.

I tried to research the issue, but there was no relevant info about it.

实际结果:

ng serve/npm 启动后，控制台出现问题:

After ng serve / npm starts there is an issue in the console:

未捕获的类型错误:ng.probe 不是函数.当前控制台状态当前角度状态

Uncaught TypeError: ng.probe is not a function. Current console state Current angular state

预期结果:

控制台没有错误

推荐答案

如果有人正在寻找替代方案:

If someone is looking for an alternative to:

ng.probe($0)

在 Ivy 中，请尝试此操作:

In Ivy, then please try this:

 ng.getComponent($0);

在这里找到，https://juristr.com/blog/2019/09/debugging-angular-ivy-console/

我想我会在这里添加这个以完成.

Thought I'd add this here for completion.

关于 ng.getComponent 的注意事项:您必须将组件标签(例如 )聚焦在开发人员工具元素中，以便它0 美元.它不会搜索父组件的层次结构(就像 ng.probe 那样).

Note about ng.getComponent: you must focus the component tag ( e.g. <app-my-component> ) in the developer tools elements so that it will be in $0. It doesn't search up the hierarchy for parent components ( like ng.probe does ).
