Error TS2315: Type 'ElementRef' is not generic

Question

I am trying to use @angular/materials in my app and it is compiling successfully, however I am getting the following error:

webpack: Compiled successfully.
ERROR in node_modules/@angular/material/button-toggle/typings/button-toggle.d.ts(136,20): error TS2315: Type 'ElementRef' is not generic.
node_modules/@angular/material/button-toggle/typings/button-toggle.d.ts(154,104): error TS2315: Type 'ElementRef' is not generic.
node_modules/@angular/material/slide-toggle/typings/slide-toggle.d.ts(53,15): error TS2315: Type 'ElementRef' is not generic.
node_modules/@angular/material/slide-toggle/typings/slide-toggle.d.ts(55,18): error TS2315: Type 'ElementRef' is not generic.

This does not seem to be a common problem, does anyone have any idea how to resolve?

Answer 1

npm uninstall @angular/material  --save
npm install @angular/[email protected] --save

It worked for me.

Angular version is 5.2.1.

Answer 2

You're using @angular/material and @angular/cdk 6RC versions (6.0.0-rc.14-29bf024), which probably depend on Angular version 6.

Either downgrade the @angular/material package to latest stable version (if you're building directly for production) or try upgrading angular to the 6.0.0-rc.6 version (if you're aiming your release after the angular 6 stable comes out).
