Question

我正在尝试使用sass在我的配置中运行gulp-ruby-sass任务，这是我得到的错误（我的配置和代码后面会出现错误）：

我对sass任务的配置如下所示：

    sass: {
        src:  app + '/scss/**/*.{sass,scss}',
        dest: app + '/css',
  options: {
    noCache: true,
    compass: false,
    sourcemap: true,
    sourcemapPath: app+'/css'
  }
},
autoprefixer: {
  browsers: [
    'last 2 versions',
    'safari 5',
    'ie 8',
    'ie 9',
    'opera 12.1',
    'ios 6',
    'android 4'
  ],
  cascade: true
},
scsslint: {
  src: [
    app + '/scss/**/*.{sass,scss}',
    ]
}

sass任务在这里：

gulp.task('sass',function(){
return sass(config.sass.src,config.sass.options)
           .pipe(plumber({errorHandler:notify.onError('<%= error.message %>')}))
           .pipe(sourcemaps.init())
           .pipe(autoprefixer(config.autoprefixer))
           .pipe(filter)
           .pipe(sourcemaps.write('.',{includeContent:false}))
           .pipe(filter.restore())
           .pipe(gulp.dest(config.sass.dest));
});

这是我的scsslint任务：

var gulp = require('gulp');
var scsslint = require('gulp-scss-lint');
var config   = require('../config').scsslint;

gulp.task('scsslint',function(){
    return gulp.src(config.src)
               .pipe(scsslint(config.options))
});

我为browser-sync和watch任务执行了这些操作：

 gulp.task('serve',['jshint','scsslint','sass'],function(){
browserSync(config);

}）;

gulp.task（＆＃39;观看＆＃39; [＆＃39;服务＆＃39]，函数（）{ gulp.watch（config.jshint，[＆＃39; jshint＆＃39;]）; gulp.watch（config.sass，[＆＃39; scsslint＆＃39;＆＃39; SASS＆＃39;]）; }）;

Answer 1

我可以从堆栈跟踪中看到两个问题：

1 - 我认为您在执行var filter = gulpFilter(['*.css', '!*.map']);

之前忘记了此pipe(filter)

2 - 如果您在此处阅读了gulp-ruby-sass的文档，则没有sourcemapPath选项：https://github.com/sindresorhus/gulp-ruby-sass

Answer 2

您正在为您的来源使用glob。来自gulp-ruby-sass README：

gulp-ruby-sass还不支持globs，只支持单个文件或目录。就像萨斯一样。

要修复，请将配置更改为：

src: app + '/scss'

使用undefined的gulp-ruby-sass错误不是一个函数
