Answer 1

If you are using ng-bootstrap then uninstall and install it again

npm uninstall @ng-bootstrap/ng-bootstrap --save

then

npm install @ng-bootstrap/ng-bootstrap --save

also, be sure that you imported the

import { NgbModule } from "@ng-bootstrap/ng-bootstrap";

in the subject Module.ts file (probably app.Module.ts )

as well as mentioned in the imports array

  imports: [
    ...
    NgbModule,
    ...
  ],

However, if you are using the traditional bootstrap be sure you did put the related @import statement in styles.css file Example

@import "~bootstrap/dist/css/bootstrap.css";

Answer 2

Trying doing an npm install bootstrap again. Maybe there was an issue that occurred during the npm installation
