I\'m working with Bootstrap 4 and Ng-Bootstrap in an Angular 4 Project,
i have linked the que bootstrap.css in my angular-cli.json this way
\"styles
I had the same problem, I used normal bootstrap 4 rather then ng-bootstrap and this way I don't need to any module in app.module file as well. it works. Below is the script add into angular.json (angular v6) and bootstrap 4+:
"scripts": ["../node_modules/jquery/dist/jquery.js",
"../node_modules/popper.js/dist/umd/popper.js",
"../node_modules/bootstrap/dist/js/bootstrap.js"]
For CSS I prefer to use Scss version so it goes like this.
"styles": [
"src/styles.scss",
"../node_modules/font-awesome/scss/font-awesome.scss"
],
and i import bootstrap into style.scss file
@import "~bootstrap/scss/bootstrap.scss";
Cheers! JK
