Cannot overwrite SASS !default variable?


Cannot overwrite SASS !default variable?

To fix this issue I’m using Gulp’s gulp-ruby-sass to generate CSS files. I'm unable to overwrite variables in open-sans.scss. Here’s the code: , Create a main.scss file like this:
code :
@import "app/assets/vendor/open-sans-fontface/open-sans.scss";
@import "app/assets/_variables.scss";
gulp.task('css', function () {
    return gulp.src(['app/assets/main.scss'])
        .pipe(sass())
        .on('error', function (err) { console.log(err.message); })
        .pipe(gulp.dest('public/css'));
});

This might help you Defining $val: 'green' locally in class1 does not alter $val: 'red' !default in mixin, because it look for global $val. At this point, no global $val has been defined.
Then global $val is defined as 'black'. After this $val in mixin look for global $val. At this point, global $val has been defined as 'black'.
code :
@mixin foo 
  $val: 'red' !default // defined locally
  .bar
    color: $val

@include foo // $val in mixin foo look for global $val. no global $val found, then 'red'

.class1
  $val: 'green'
  @include foo // $val in mixin foo look for global $val. no global $val found, then 'red'
  color: $val // local $val 'green'
  .class11 
    @include foo // $val in mixin foo look for global $val. no global $val found, then 'red'

$val: 'black' // defined globally at the first time

.class2 
  @include foo // $val in mixin foo look for global $val. $val found, 'black'

.class3
  $val: 'blue' // change the gobal $val
  @include foo // $val in mixin foo look for global $val. $val found, 'blue'

.class4
  @include foo // $val in mixin foo look for global $val. $val found, 'blue'
SASS - Default values for variable arguments

it helps some times Variable arguments was added in Sass 3.2. , Your solution does not work. When used with no arguments, e. g.
code :
.foo { @include transition; }
() isn't a valid CSS value.
@mixin transition($values...) {

  // Setting the default value
  @if length($values) == 0 {
    $values: all 0.3s ease;
  }

  -webkit-transition: $values;
  -moz-transition: $values;
  -ms-transition: $values;
  -o-transition: $values;
  transition: $values;
}

To fix the issue you can do The solution as stated by @seven-phases-max is to move the variables.less file after my components file. e.g.
Files
code :
@import "component.less";
@import "variables.less";
body {
  background-color: @color
}
Sass Variable Argument and Variable with default value in the same Mixin

Any of those help I don't think variable arguments can have a default value, but you can check if the variable exists, and if not then set its value:
code :
@mixin p($size: 20px, $font-fam...){
    @if length($font-fam) == 0 {
        $font-fam: "Helvetica", sans-serif;
    }
    font-family: $font-fam;
    font-size: $size;
}
Is there any way to use sass instead of node-sass (default for sass-loader) in Nuxt.js?

it helps some times Its already pointed on documentation.
nuxt.config.js:
code :
build: {

  ...

  loaders: {
    sass: {
      implementation: require('sass')
    },
    scss: {
      implementation: require('sass')
    }
  }

  ...

}
