Updated to Angular 11. Getting Error: Angular CLI v10.1.0 and later (and no `tsconfig.base.json`) is required in order to run this schematic.

I updated my project to Angular 11.

I ran this and got the following error. It did not install anything. How do I fix this?

ng add @angular-eslint/schematics

Error: Angular CLI v10.1.0 and later (and no `tsconfig.base.json`) is required in order to run this schematic. Please update your workspace and try again.

hi. i had the same issued after I updated angular to the 11 version using --force params. I fixed it using this

ng update @angular/cli --migrate-only --from 9 --to 11
ng update @angular/core --migrate-only --from 9 --to 11

@JamesHenry maybe u can add this do the documentation too =)

I got it working, but I had to delete tsconfig.base.json before running ng add @angular-eslint/schematics and ng g @angular-eslint/schematics:convert-tslint-to-eslint {{YOUR_PROJECT_NAME_GOES_HERE}}

I had to restore tsconfig.base.json before running the last line, npx ng lint {{YOUR_PROJECT_NAME_GOES_HERE}}
