When I run ng add @angular/material I get

"Installing packages for tooling via npm."

and then

"An unhandled exception occurred: npm WARN deprecated req...@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

npm ERR! Unexpected end of JSON input while parsing near '...nyc":"^11.4.1","sinon'"

I yarn-upgraded angular-cli, yarn-upgraded npm but still get the error.

I try to add angular material to an existing application: "@angular/core": "~8.2.9".

What is the problem here??

ok, I get my steps from https://material.angular.io/guide/getting-started. Although not mentioned I figured out I have to do "yarn add @angular/material" first, _Then_ do ng add @angular/material.

I get the questions from the schematic runner then the updating of my package.json starts.Buuuut I still get the error. Full output below:

yarn add @angular/material @angular/cdk @angular/animations

yarn add v1.22.0
