Module build failed boostrap

[raxkin]

I just clone the project and installed dependences. When i run npm run dev it throws 24 errors, all for the same problem:

 error  in ./src/components/vuestic-components/vuestic-modal/VuesticModal.vue

Module build failed: 
$link-hover-color:      darken($link-color, 15%) !default;
                       ^
      Argument `$color` of `darken($color, $amount)` must be a color

Backtrace:
	node_modules/bootstrap/scss/_variables.scss:168, in function `darken`
	node_modules/bootstrap/scss/_variables.scss:168
      in /dev/vue/node_modules/bootstrap/scss/_variables.scss (line 168, column 25)

It gives the same error but for other components.

2 days ago i cloned the same project and it works fine, but today no

Also it give this error:

 error  in ./src/App.vue

Module build failed: 
    @include button-size($btn-padding-y, $btn-padding-x, $font-size-base, $btn-border-radius);
            ^
      Mixin button-size is missing argument $border-radius.

@raxkin, thanks you for this issue! Problem was in failure of reverse compatibility of bootstrap 4 beta with bootstrap 4 alpha:)

Can it work with beta?
