我试图在本地测试EventCloud多租户Saas（.Net Core + Angular SPA），但它会在调试日志文件中引发此错误

我已经在全球范围内安装了Angular Cli，所以我在本地更新了角度cli和打字稿，但随后会显示
The serve command requires to be run in an Angular project, but a project definition could not be found.

npm ERR! errno 1

在更新Angular Cli时，我遵循了this和this。另外，我确实从here克隆了源项目，并遵循了this准则。记住服务器端核心项目运行成功，我能够看到列出了所有应用程序端点的Swagger Api Index。
答案 0 :(得分：0)
我从here解决了我的问题。
Angular 6会寻找angular.json而不是angular-cli.json。
您需要更新您的@ angular / cli。
我确实使用以下命令更新了所有软件包，并且也更新了所有依赖项。以消除与其他软件包的所有兼容性问题。
如果要启动您的应用程序或演示应用程序，请遵循以下步骤。如果您要针对生产应用执行此操作，请格外小心。
//更新您的package.json
npm install -g npm-check-updates
//使用ncu更新程序包// ncu用于显示//用于重写程序包。json
ncu -u
更新您的@ angular / cli以将您的应用程序修改为与angular 6兼容
ng update @angular/cli
npm install
npm start
