我有一个带有Knockout框架的SPFx Web部件。它是为本地SharePoint（V1.1.0）开发的。在SharePoint库中部署了所有资产。应用程序在Chrome中运行正常。但是在IE中，Web部件未加载到页面中。即使我没有任何控制台日志/错误。如果在开发人员控制台打开的情况下刷新页面，则该页面有效。
即使从捆绑的JS中删除了控制台日志，我也删除了该应用程序中的所有控制台日志。仍未加载Web部件。
然后我认为加载JS的顺序可能有问题。因此，我已经注释了所有代码和包导入语句。但没有运气。
在“一些文章”中，我发现母版页可能有问题。因此，我已删除了自定义母版，然后又重新设置母版。但是仍然有问题。
然后，我在打开开发人员控制台的情况下加载了页面，发现控制台中存在问题
对象不支持属性或方法“警告”
，它是从 sp-classic-page-assembly_en-us.js 抛出的。
有时，我还可以从 sp-classic-page-assembly_en-us.js 看到堆栈溢出错误。
下面是示例ViewModel.ts文件代码。
