I installed bootstrap in angular 8 but not working.Why?

I installed bootstrap 3.4.1 and jquery in my project.There were no errors.Versions are showing in package.json I have also added the bootstrap file path in angular.json file .But bootstrap themes are not working at all.

I followed this video to install bootsrap: https://www.youtube.com/watch?v=KaTtlGSJ0QE

the installation went well, but validation using http://localhost:4200/node_modules/bootstrap/dist/css/bootstrap.min.css gave some errors in console.

angular.json:

"styles": [
              "src/styles.scss",
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
            ],
            "scripts": [
              "node_modules/bootstrap/dist/js/bootstrap.min.js",
              "node_modules/jquery/dist/jquery.min.js"
            ]

html:

<div class="container-fluid ">
      <h1>Login</h1>
      <form  [formGroup]="loginForm" (ngSubmit)="onSubmit()">

          <div class="form-group">
            <label for="userName">User Name : </label>
            <input formControlName="userName" type="text" class="form-control" >
          </div>
          <div class="form-group">
              <label for="password">Password : </label>
              <input  formControlName="password" type="password" class="form-control" >
          </div>

            <button class="btn btn-primary" type="submit"  >Login</button>

        </form>
        {{loginForm.value | json}}
    </div>

The o/p does not contain any bootstrap stylisation as expected.

If you install Bootstrap while live server is running, the bootstrap changes will not apply. Stop the live-server and start again

Angular-9, It works for me by removing '/' and the beginning of the path

 "scripts": [ "node_modules/bootstrap/dist/js/bootstrap.js"]

all the solutions that involve relative paths in the test section of the angular.json file will fail.

The solution I used is:

I added the relative paths in the project block under build block. My Angular version is:

         _                      _                 ____ _     ___
    / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
   / △ \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |
  / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |
 /_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
                |___/

          }
        }
      }
    }
  },
  "defaultProject": "first-application"
}

The mistake I did before was adding the css and scripts at the test block, please recheck the whole angular.json file and ensure you're in the right block and use a relative path to the node modules as shown above.

Better if you update your angular cli to the latest version.

Change angular.json like this:

"styles": [
   "node_modules/bootstrap/dist/css/bootstrap.min.css",
   "src/styles.scss"
],
"scripts": [
   "node_modules/jquery/dist/jquery.min.js", // <- jQuery goes first
   "node_modules/bootstrap/dist/js/bootstrap.min.js"
]

Also you can compare your code with authors version here. Text version of that tutorial.

Do not use "/" when you are importing from node_modules and you should import your style after all others to increase priority of it.

It should be:

            "styles": [
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
              "src/styles.scss",
            ],
            "scripts": [
              "node_modules/jquery/dist/jquery.min.js"
              "node_modules/bootstrap/dist/js/bootstrap.min.js",
            ]
