Answer 1

you should install neccessary @angular/cdk library to correct use of the newest @angular/material.

You can do this by command:

npm install --save @angular/material @angular/cdk

Answer 2

Get into the Workspace or Angular project you are working with, open command prompt and run the below command:

npm install --save @angular/material @angular/cdk

If the error is still not gone, try clearing the cache by the given command :

npm cache clear --force

Another approach to clean the cache is by manually deleting it from the file system at

C:\Users\%USER_PROFILE_NAME%\AppData\Roaming\npm-cache

Try deleting everything from the above location then rerun

npm install --save @angular/material @angular/cdk

Hopefully this should solve your issue and ngServe would show the message about successful compilation of project.

Answer 3

There are questions the package stops and asks you before it installs, and I did not realize that. I started to work in another terminal/window. When I got those error messages, I did not realize the package was hanging on those questions in the first terminal, and once I answered them, the package installed and those errors went away.
