+The first line is just an auxiliary information printed by qiankun through console.error, which is used to help users quickly know which js has an error, not a real exception. The real exception information is on the second line.
+
+For example, such an error indicates that when qiankun was executing the http://localhost:9100/index.bundle.js of the sub application, this js itself threw an exception. The specific exception information is Uncaught TypeError: Cannot read property 'call' of undefined.

+Sub-application exceptions can be attempted to be resolved through the following steps:

+Check the error js for syntax errors according to the specific exception information, such as missing semicolons, dependence on uninitialized variables, etc.
+Whether it depends on global variables provided by the main application, but the main application is not actually initialized.
+Compatibility issues. The js itself of the sub-application has syntax compatibility issues in the current runtime environment.

 ## How to load micro apps on a routing page of the main app
 
 It must be ensured that the routing page of the main app is also loaded when the micro app is loaded.

 如果仍然报错，检查容器 DOM 是否放在了主应用的某个路由页面，请参考[如何在主应用的某个路由页面加载微应用](#如何在主应用的某个路由页面加载微应用)。

+其中第一行只是 qiankun 通过 `console.error` 打印出来的一个辅助信息，目的是帮助用户更快的知道是哪个 js 报错了，并不是真的异常。真正的异常信息在第二行。
+
+比如上图这样一个报错，指的是 qiankun 在执行子应用的 `http://localhost:9100/index.bundle.js` 时，这个 js 本身抛异常了。而具体的异常信息就是 `Uncaught TypeError: Cannot read property 'call' of undefined`.
+
+子应用本身的异常，可以尝试通过以下步骤排查解决：
+1. 根据具体的异常信息，检查报错的 js 是否有语法错误，比如少了分号、依赖了未初始化的变量等。
+2. 是否依赖了主应用提供的全局变量，但实际主应用并未初始化。
+3. 兼容性问题。子应用这个 js 本身在当前运行环境存在语法兼容性问题。

 ## 如何在主应用的某个路由页面加载微应用
 
 必须保证微应用加载时主应用这个路由页面也加载了。
