angular6 – 从角度5更改为角度6时,无法找到本地工作空间文件(‘angular.json’)

npm install --save-dev @angular/cli@latest
ng update @angular/cli
ng update @angular/core
ng update @angular/material
ng update rxjs

但是当运行ng服务时,错误会不断出现,如下所示

我被告知.angular-cli.json被一个新的替换：angular.json,但架构不再是旧版本,

这是我当前的angular-cli.json,我怎么能改成angular.json
