Since Angular 10 migration: creating new libraries fails with missing tsconfig.base.json

[MichaelLangbein]

Describe the bug

With the current master branch, executing

npx ng generate library <library-name>

fails with the error-message:

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

A little research brought up evidence that others, too, have experienced a similar issue, and - with a little luck - a way to resolve it. In short, it seems that angular's update did not separate our tsconfig.json into a tsconfig.base.json (which all projects inherit from) and a stub tsconfig.json (which seems to only remain there for the sake of IDE's like VSCode).

I'll attempt to properly split our config in those two files.

To Reproduce

From the root-directory, run

npx ng generate library <library-name> (--dry-run)

Expected behavior

Putting it a little matter-of-fact-ly: generating libraries should work.

Versions

App

• Angular: [10.0.8]
• Node: [v12.13.0]
• Clarity: [3.1.5]
• UKIS: [7.1.0]

Device:

• Type: [Notebook]
• OS: [Windows]

Additional context

As a side note, this issue only occurs when generating libraries. I didn't encounter any errors in e.g. generating components - which makes sense, since new components don't need a new tsconfig-file.
