NPM errors and how these are stated is not my strong suit of understanding, would love if someone could help me out and point me in the right direction here.

Thanks!

Heres my package.json file aswell, im assuming its something in there by the way the error is formed/stated.

CodePudding user response：

Moving the comment to an answer per OP's request and so that the question can be marked resolved.

Looking at the Github releases page (accessed on 10/12/22 for v 13.0.0) the maximum support for the library currently is Angular 14.1, where as you are using 14.2.2. This seems to be a version compatibility issue (essentially the library is trying to pull an older version of Angular and you are getting a conflict)

You either have to downgrade you Angular version or use something else

Run npm update before installing ng bootstrap in your vs code terminal, that will fix it
