Cannot find tsconfig.base.json when generating a new app

Current Behavior

When I run nx g @nrwl/angular:app app in my freshly created nx workspace and select SASS for stylesheets I’m getting the following error: Cannot find base TypeScript configuration file 'tsconfig.base.json

Expected Behavior

The app gets created as expected.

Steps to Reproduce

npx create-nx-workspace@latest with the Angular preset nx g @nrwl/angular:app app with SASS and routing

Failure Logs

Cannot find base TypeScript configuration file 'tsconfig.base.json'.

Environment

Globally:

@angular/cli@9.1.10
@nrwl/cli@9.5.1

nx report in my project:

I get the same problem on Angular 10, I’m using a workspace with 4 projects, I’m trying to add a new project

ng generate application xxxx ? Would you like to add Angular routing? Yes ? Which stylesheet format would you like to use? CSS Cannot find base TypeScript configuration file ‘tsconfig.base.json’.

Dependencies I use: “@angular/animations”: “~10.0.8”, “@angular/cdk”: “^10.1.2”, “@angular/common”: “~10.0.8”, “@angular/compiler”: “~10.0.8”, “@angular/core”: “~10.0.8”,

I got the solution, for unknow reason, the upgrade from 9 to 10 did non rename tsconfig.json to tsconfig.base.json. I’ve do it myself, and then modified the variuos references in workspace. After that, adding a new project was succesful.

I was running into the same issue when upgrading from angular9 to angular10. My problem was that I only upgraded the @angular/core and forgot to upgrade @angular/cli separately. I used to --migrateOnly on the ng update which helped to fix the missing tsconfig.base.json without doing the work by hand.
