  • try to run ng add @ng-bootstrap/ng-bootstrap --force command. Commented Jan 13, 2023 at 6:14
  • No, I wanted to fix the issue rather than force it. Thanks anyway. Commented Jan 16, 2023 at 3:19
  • No fixes for this. I have moved on though and just created a new project and added bootstrap first and all ok so don't really need this anymore. What is the protocol with the question? Commented Jan 18, 2023 at 6:39
  • I have the same issue. I'm using angular 15.1.0 in a new project, and i'm getting the same error. I tried using --force and it didn't solve the problem. Commented Feb 13, 2023 at 14:29

Here you have related the versions of ng-bootstrap for each version of Angular.

ng-bootstrap Angular bootstrap.css Poper
9.x.x         11.0.0    4.5.0   
10.x.x        12.0.0    4.5.0   
11.x.x        13.0.0    4.6.0   
12.x.x        13.0.0    5.0.0       2.10.2
13.x.x        14.1.0    5.2.0       2.10.2
14.x.x        15.0.0    5.2.3       2.11.6

So, if your app is in Angular 13, e.g. you need instal ng-bootstrap 12.x.x

ng add @ng-bootstrap/[email protected]

See that in this link you have the "changelog", so choose the bigger version according your version of Angular

NOTE: Perhaps you prefer upgrade your app to the most higher Angular version

Thanks sounds promising. I am using Angular 15.1.0 and tried ng-bootstrap 14.0.0 and 14.0.1 but no luck. I did create a brand new Angular project and then add bootstrap straight away before anything else and that was ok just struggling with an existing app.

I think you can try to delete "node_modules" folder and "package-lock.json" as well, and then run npm i

Install bootstrap using npm : npm i bootstrap . And then in angular.json file-> inside "styles" array add "node_modules/bootstrap/dist/css/bootstrap.min.css" and inside script array add "node_modules/bootstrap/dist/js/bootstrap.min.js"

it's related to ng-bootstrap, not to bootstrap.
