gulp-ruby-sass 错误与未定义不是一个函数

Question

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

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))
});

我在browser-sync和watch任务中执行它们：

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

}）;

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

Answer 1

从堆栈跟踪中可以看到 2 个问题：

1 - 我想你在做pipe(filter)之前忘记了这个var filter = gulpFilter(['*.css', '!*.map']);

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

Answer 2

您正在为源使用 glob。来自大口大口的红宝石自述文件：

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

要解决此问题，请将您的配置更改为：

src: app + '/scss'
