Answer 1

I had same issue, i solved it by switching npm reigistry from the list of given npm registry.

List of Npm registry:

https://registry.npmjs.org/ (Dfault One)

http://r.cnpmjs.org/

https://registry.npm.taobao.org/

https://registry.nodejitsu.com/

http://registry.mirror.cqupt.edu.cn

https://skimdb.npmjs.com/registry

https://npm.open-registry.dev/ (https://open-registry.dev)

To switch just type

npm config set registry "https://registry.npmjs.com/"

Replace the registry url with the above urls check which one works for you.

Then:

npm cache clear --force

solved.

you can then Install
