angular2-cli gives @multi styles error

Question

I started using angular2-cli recently and created a new project. I wanted to use bootstrap in my project hence I installed bootstrap and then wanted to import the bootstrap css file like it is shown in the the angular2-cli guide here. https://github.com/angular/angular-cli#global-library-installation After running ng serve I get the following error.

ERROR in multi styles Module not found: Error: Can't resolve '/home/krishna/angular2_migrate/webui/node_modules/bootstrap/dist/css/bootstrap.min.css' in '/home/krishna/angular2_migrate/webui/node_modules/angular-cli/models' @ multi styles

What am I doing wrong ?

Answer 1

Add ../ before path.

In angular-cli.json,

"styles": [
  "../node_modules/bootstrap/dist/css/bootstrap.min.css",
  "styles.scss"
]

Update

In angular7, there is angular.json file and you do not need to add ../ before path

Answer 2

In Angular 7 the file is called 'angular.json'.

Make sure you got the right extension set for the "styles" option. In my case I installed the Angular CLI with the SCSS option but the extension was set as SASS by default.

       "styles": [
          "src/styles.scss" // default was: src/styles.sass
        ],

Answer 3

I am using Angular 6 so my filename is angular.json, but I was able to resolve the similar issue by removing the "../" path that it was asking for. Below is my setup for adding bootstrap and jquery to my angular app.

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

Note: for jquery i needed the "../" while bootstap did not require it.

Alternate based on issues I had:

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

Also, this article holds multiple alternate options on setting it .
