gulp plugin gulp-ruby-sass没有编译

Question

gulp插件gulp-ruby-sass(https://github.com/sindresorhus/gulp-ruby-sass)给出不编译,终端中的错误信息就像这样

错误:必须提供模式

这是gulpfile.js的详细信息

var gulp = require('gulp'),
  uglify = require('gulp-uglify'),
    sass = require('gulp-ruby-sass');

    gulp.task('styles', function (argument) {
        gulp.src('sass/app.scss')
            .pipe(sass())
            .pipe(gulp.dest('css/'));
    });

Answer 1

gulp-ruby-sass语法已更改:

instead of:                          it is now:

gulp.task('styles', function (){     gulp.task('styles', function (){
    gulp.src('sass/app.scss')            return 
        .pipe(sass())                        sass('sass/app.scss')
        .pipe(gulp.dest('css/')              .pipe(gulp.dest('css/')
    ;                                    ;
});                                  }); 

请检查出来并将问题标记为已解决.

该负责人一饮而尽,红宝石萨斯文件说,它应该这样做:

var gulp = require('gulp');
var sass = require('gulp-ruby-sass');    

gulp.task('sass', function () {
  return sass('source/file.scss')
    .on('error', sass.logError)
    .pipe(gulp.dest('result'));
});
