A known bug, you can observe it here: https://github.com/angular/angular-cli/issues/22333

As they mention, you can:

  1. Updated npm install --save --legacy-peer-deps
  2. Set yarn as default package manager. Instruction https://codinglatte.com/posts/angular/setup-angular-touse-yarn-package-manager

  • Folks, I was facing a dependency conflict with Angular 12.2.1 (in the project) and the root angular installation of Angular 12.2.2. The ng update command mentioned above helped me. It upgraded my local angular installation to 12.2.2 and I could install bootstrap. – Saswata Mishra Mar 13 '23 at 12:30

Run this command

npm install --save --legacy-peer-deps

If you're facing issues installing ng-bootstrap using npm, you might want to try installing it with yarn instead. Here's how:

First, make sure you have yarn installed globally by running:

npm install -g yarn

Once you have yarn, you can install ng-bootstrap by running:

yarn add ng-bootstrap

This should install ng-bootstrap and its dependencies successfully.

I hope this helps!
