我用角度创建了asp.net core 2.2项目， 并将角度cli更新为8.低于错误
The NPM script 'start' exited without indicating that the Angular CLI was listening for requests. The error output was: The serve command requires to be run in an Angular project, but a project definition could not be found
我从angular.json文件中删除了--extract，但仍然抛出错误，
任何人都可以指导如何安全地将asp.net core cli版本升级到最新版本
我当前的angular.json文件是
