I connect Bootstrap to the project via SASS:

@import "../../node_modules/bootstrap-sass/assets/stylesheets/bootstrap"
@include font-face(Glyphicons, ../../node_modules/bootstrap-sass/assets/fonts/bootstrap)

The SASS compiler crashes with an error:

Error: Invalid CSS after "...ace(Glyphicons,": expected expression (e.g. 1px, bold), was "..\\..\\node_modules\\"
        on line 7 of src/style/main.sass
>> @include font-face(Glyphicons, ..\..\node_modules\bootstrap-sass\assets\fonts\
   -------------------------------^

    at options.error (C:\Sites\Roboschool\node_modules\node-sass\lib\index.js:291:26)

Is there any other way to connect normally?
Or am I wrong somewhere?

Answer 1

Glyphicons CDN
HTML:
CSS:
Bootstrap CDN with Font Awesome
Font Awesome CDN Font Awesome
itself Does not require any fonts to be included.( )
@include font-face

Answer 2

What for? Take the minimal version and just add? Are you going to remove / change the icons?
And it’s even better to connect from somewhere in the CDN, maybe someone already has it in the cache ... Saving on loading
