gulp编译不同路径的scss

var gulp = require('gulp');
var compass = require('gulp-compass');

gulp.task('compass', function() {
    ['./', './mobile/', './ws-ydpm/'].forEach(function(dir){
        gulp.src(dir+'scss/*.scss')
            .pipe(compass({
                sass: dir+'scss/',
                css: dir+'css/'
            }))
            .pipe(gulp.dest(dir+'css'));
    })
});


gulp.task('default', function() {
    gulp.start('compass');
    gulp.watch('./**/*.scss', function() {
        gulp.start('compass');
    });
});

注意：要用这个gulp的时候，它forEach的资料夹都要有，而且里面也要有scss/css资料夹及檔案…
