I am new to angular. I just installed angular material and angular animations in my small project and got some of the errors

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

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.


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