在离子项目中设置SASS

Question

Following is the command which I run to implement SASS in my project -

ionic setup sass

After node dependencies installed, I run - ionic serve command and tried changing - $positive with teal color code but it is not reflecting even if I reload the page in browser, though If I make change to $positive in _variables.scss after rerunning the command ionic serve it is showing the color.

I believe I only need to make change in scss/ionic.app.scss and it should automatically reflect the changes.

Let me know what I am missing here.

FYI - Following is the CSS in my index.html

<!-- compiled css output -->
<link href="css/ionic.app.css" rel="stylesheet">

Following is my gulpfile -

var gulp = require('gulp');
var gutil = require('gulp-util');
var bower = require('bower');
var concat = require('gulp-concat');
var sass = require('gulp-sass');
var minifyCss = require('gulp-minify-css');
var rename = require('gulp-rename');
var sh = require('shelljs');

var paths = {
  sass: ['./scss/**/*.scss']
};

gulp.task('default', ['sass']);

gulp.task('sass', function(done) {
  gulp.src('./scss/ionic.app.scss')
    .pipe(sass())
    .on('error', sass.logError)
    .pipe(gulp.dest('./www/css/'))
    .pipe(minifyCss({
      keepSpecialComments: 0
    }))
    .pipe(rename({ extname: '.min.css' }))
    .pipe(gulp.dest('./www/css/'))
    .on('end', done);
});

gulp.task('watch', function() {
  gulp.watch(paths.sass, ['sass']);
});

gulp.task('install', ['git-check'], function() {
  return bower.commands.install()
    .on('log', function(data) {
      gutil.log('bower', gutil.colors.cyan(data.id), data.message);
    });
});

gulp.task('git-check', function(done) {
  if (!sh.which('git')) {
    console.log(
      '  ' + gutil.colors.red('Git is not installed.'),
      '\n  Git, the version control system, is required to download Ionic.',
      '\n  Download git here:', gutil.colors.cyan('http://git-scm.com/downloads') + '.',
      '\n  Once git is installed, run \'' + gutil.colors.cyan('gulp install') + '\' again.'
    );
    process.exit(1);
  }
  done();
});

My CSS in www folder -

Now you can in the 3rd screenshot I am having _variables.scss (at last) in which I am changing values, but it is not watching my changes. Once I did ionic serve it is showing the color change then.

What you need to do is add the !default flag to the colour you're overriding, that way it will overwrite the Ionic ones.

An example:

$light:                           #fff !default;
$stable:                          #f8f8f8 !default;
$positive:                        #387ef5 !default;
$calm:                            #11c1f3 !default;
$balanced:                        #33cd5f !default;
$energized:                       #ffc900 !default;
$assertive:                       #9D0000 !default;
$royal:                           #886aea !default;
$dark:                            #25272A !default;
$light-black:                     #303134 !default;
$gray:                            #939393 !default;
$light-gray:                      #BFBFBF !default;
$dark-brand:                      #0A9693 !default;
$danger-dark:                     #E0483E !default;
$facebook:                        #3B5998 !default;

PS: This configuration works with Ionic being imported after the declaration of these variables
