我有一个托管在.net core 3.1应用程序中的Angular应用程序。我已按照官方指南从8升级到9，现在无法构建我的应用程序。我收到以下错误：
“未找到模块：错误：无法解析'@ angular / cdk / layout / breakpoints'”，“字段“浏览器”不包含有效的别名配置，解析为模块，在未找到描述文件中查找模块字段“浏览器”不包含有效的别名配置找不到描述文件，没有扩展名字段“浏览器”不包含有效的别名配置/ @ angular / cdk / layout / breakpoints不存在.ts“
我在@angular/material/core/common-behaviors，@angular/material/core/datetime和@angular/material/core/ripple上遇到相同的错误。
我已包含所有我认为可能会有所帮助的文件。我一直在尝试修复此问题，并且用尽了所有想法。这非常令人沮丧，请帮助。

尝试：
node_modules文件夹npm i / yarn npm install @angular/cli -g ng update @angular/cli @angular/core --force ng update --all --force 如果您有棱角材料，请在最后一个命令中添加
@angular/material
如果要通过git commit查看更改，请添加--create-commits

以防万一
Angular编译器中的错误需要TypeScript> = 3.6.4和<3.9.0，但是找到了3.9.5。
尝试 npm我typescript@3.8
