ruby-sass 是依赖 ruby 的，你确定 ruby 环境无误么？建议还是直接用 node-sass 性能也更好一些。

你没有一个叫scss的变量，看这里:

gulp.task('scss', function() {
    return gulp.src(['stc/scss/*.scss','!stc/scss/extend/{reset,test}.scss']) 
               .pipe(plumber({errorHandler: notify.onError('Error: <%= error.message %>')})) 
               .pipe(sass()) //这里不对,应该是sass吧
               .pipe(gulp.dest("stc/css")) 
               .pipe(reload({stream: true}));
});
