Warning while installing Angular Material

Question

I installed Angular Material and noticed several warnings on the console. Do I have incompatible or missing libraries?

You are using @angular/material in 6.1.0. This version is designed to work with Angular 6. It appears that you are using an earlier Angular version.

For Angular 5 you could use @angular/material in version 5.x.x by updating your package.json as follows:

"dependencies": {
    ...
    "@angular/cdk": "^5.2.5",
    "@angular/material": "^5.2.5",
    ...
 },
