ruby - gulp-ruby-sass 错误错误：必须提供模式

Question

我正在使用带有 PostCSS 的 Ruby sass。这是我的 gulp css 任务。

gulp.task('css', function () {
    var processors = [
    short,
    rucksack,
    postcssmodules
    ];
    return gulp.src('./css/src/*.scss')
        .pipe(postcss(processors, {syntax: scss}))
        .pipe(sass().on('error', sass.logError))
        .pipe(gulp.dest('./dest'));
});

我得到的错误

You cannot use gulp-ruby-sass in a .pipe(). Read the docs:

Use gulp-ruby-sass instead of gulp.src to compile Sass files.

You'll have to use sass() before your postcss():

gulp.task('css', function() {
  var processors = [
    short,
    rucksack,
    postcssmodules
  ];
  return sass('./css/src/*.scss')
   .on('error', sass.logError)
   .pipe(postcss(processors))
   .pipe(gulp.dest('./dest'));
});
