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 .

Answer 4

give the path like "./node_modules/bootstrap/dist/css/bootstrap.min.css" not like "../node_modules/bootstrap/dist/css/bootstrap.min.css"

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

Answer 5

In my case the error was was because i had

    "styles":[
      "styles.css"
    ]

in my .angular-cli.json

i solved it by manually typing the path of my all SCRIPTS and CSS ..ie for example

    "styles":[
      "styles/bootstrap.scss",
      "styles/app.scss",
     ]

Paths in angular-cli.json are relative to the project root (src/ normally). For instance, you have the src/styles.css file, but in angular-cli.json it's listed only as styles.css.

Answer 6

give the path like "./node_modules/bootstrap/dist/css/bootstrap.min.css" not like "../node_modules/bootstrap/dist/css/bootstrap.min.css"

here is the fix for me. in you current directory you have a hidden file called .angular-cli.json open that and change the "style.sass" to "style.css: run ng build and you are done.

The solution below worked for me, as it seems there is a bug in bootstrap 4.0:

npm uninstall bootstrap --save

then install

npm install bootstrap@3.3.7 --save

我遇到了同样的问题，但我通过提供如下"styles": [ "F:/Angular2Projects/Angular/myapp/node_modules/bootstrap/dist/css/bootstrap.min.css", "F:/Angular2Projects/Angular/my-app/src/styles.css" ],文件的完整路径来解决该问题"styles": [ "F:/Angular2Projects/Angular/myapp/node_modules/bootstrap/dist/css/bootstrap.min.css", "F:/Angular2Projects/Angular/my-app/src/styles.css" ],

Answer 11

You just need to add the below mentioned code in style.css

@import url('https://unpkg.com/bootstrap@3.3.7/dist/css/bootstrap.min.css');

Hope it helps

Answer 12

Copy and paste the following in your {}angular.json file should work perfect.
