Gulp没有错误，但SASS没有编译成CSS

Question

please help I'm not getting any errors but this code will not create the compiled css from the scss file. I am writing the code within the underscore WP theme if that matters I don't think it should though. I have all the dependences loaded on my machine. I will attach my JSON in the case someone would need to see that.

    var themename = 'taylerco';

var gulp = require('gulp'),
    //prepare and optimize code
    autoprefixer = require('autoprefixer'),
    browserSync = require('browser-sync').create(),
    image = require('gulp-image'),
    jshint = require('gulp-jshint'),
    postcss = require('gulp-postcss'),
    sass = require('gulp-sass'),
    sourcemaps = require('gulp-sourcemaps'),

   //only work with new or updated files
   newer = require('gulp-newer'),

   //name of working theme folder
   root = '../' + themename + '/',
   scss = root + 'sass/',
   js = root + 'js/',
   img = root + 'images/',
   languages = root + 'languages/';

// css via sass and autoprefixer
gulp.task('css', function(){
    return gulp.src(scss + '{style.scss,rtl.scss')
    .pipe(sourcemaps.init())
    .pipe(sass({
        outputStyle:'expanded',
        indentType:'tab',
        indentWidth:'1'
    }).on('error', sass.logError))
    .pipe(postcss([
        autoprefixer('last 2 versions', '> 1%')
    ]))
    .pipe(sourcemaps.write(scss + 'maps'))
    .pipe(gulp.dest(root));
});

//optimize images through gulp-image
gulp.task('images', function(){
    return gulp.src(img + 'RAW/**/*.(jpg,JPG,png)')
    .pipe(newer(img))
    .pipe(image())
    .pipe(gulp.dest(img));
});

//javascript
gulp.task('javascript', function(){
    return gulp.src([js + '*.js'])
    .pipe(jshint())
    .pipe(jshint.reporter('default'))
    .pipe(gulp.dest(js));

});

//watch everything
gulp.task('watch', function(){
    browserSync.init({
        open: 'external',
        proxy: 'localhost:8888',
        port: 8080
    });
    gulp.watch([root + '**/*.css',root + '**/*.scss'], ['css']);
    gulp.watch(js + '**/*.js', ['javascript']);
    gulp.watch(img + 'RAW/**/*.(jpg,JPG,png)', ['images']);
    gulp.watch(root + '**/*').on('change', browserSync.reload);
});

//default talk (runs at initiation: gulp --verbose)
gulp.task('default', ['watch']);

There seems to be a typo in your syntax.

Change

 return gulp.src(scss + '{style.scss,rtl.scss')

To

 return gulp.src(scss + '{style.scss,rtl.scss}')
