我有一个Angular应用程序，它托管在.net core 3.1应用程序中。我按照官方指南从8升级到9，现在我的应用程序无法构建。我得到了以下错误：
“找不到模块：错误：无法解析'@angular/cdk/layout/breakpoints'”，“字段'browser'不包含有效的别名配置，将模块解析为没有说明文件的模块 looking for modules in No description file found Field 'browser' doesn't contain a valid alias configuration No description file found no extension Field 'browser' doesn't contain a valid alias configuration /@angular/cdk/layout/breakpoints doesn't exist .ts“
对于@angular/material/core/common-behaviors、@angular/material/core/datetime和@angular/material/core/ripple，我也遇到了同样的错误。
我已经包括了我认为可能有用的所有文件。我一直在努力修复这个问题，但是已经无计可施了。这非常令人沮丧，请帮忙。
