Gulp-ruby-sass错误：

Question

The gulp plugin gulp-ruby-sass doesn't work when compiling sass files .

'use strict';

    var path = require('path');
    var gulp = require('gulp');
    var conf = require('./conf');

    var browserSync = require('browser-sync');

    var $ = require('gulp-load-plugins')();

    var wiredep = require('wiredep').stream;
    var _ = require('lodash');

    gulp.task('styles-reload', ['styles'], function() {
      return buildStyles()
        .pipe(browserSync.stream());
    });

    gulp.task('styles', function() {
      return buildStyles();
    });

    var buildStyles = function() {
      var sassOptions = {
        style: 'expanded'
      };

      var injectFiles = gulp.src([
        path.join(conf.paths.src, '/app/**/*.scss'),
        path.join('!' + conf.paths.src, '/app/index.scss')
      ], { read: false });

      var injectOptions = {
        transform: function(filePath) {
          filePath = filePath.replace(conf.paths.src + '/app/', '');
          return '@import "' + filePath + '";';
        },
        starttag: '// injector',
        endtag: '// endinjector',
        addRootSlash: false
      };

      var cssFilter = $.filter('**/*.css', { restore: true });

      return gulp.src([
        path.join(conf.paths.src, '/app/index.scss')
      ])
        .pipe($.inject(injectFiles, injectOptions))
        .pipe(wiredep(_.extend({}, conf.wiredep)))
        .pipe($.rubySass(sassOptions)).on('error', conf.errorHandler('RubySass'))
        .pipe(cssFilter)
        .pipe($.sourcemaps.init({ loadMaps: true }))
        .pipe($.autoprefixer()).on('error', conf.errorHandler('Autoprefixer'))
        .pipe($.sourcemaps.write())
        .pipe(cssFilter.restore)
        .pipe(gulp.dest(path.join(conf.paths.tmp, '/serve/app/')));
    };

This is a tricky one. Looks like you're using generator-gulp-angular and selected ruby-sass . Unfortunately, the API of gulp-ruby-sass has changed in September (with their 2.0.0 release) and the generator wasn't updated since. In a nutshell: the new API needs the source files passed into the stream factory method .pipe($.rubySass([**SOURCE FILES HERE**], sassOptions)).on('error', conf.errorHandler('RubySass')) which is basically not possible when combining the build chain with other plugins like inject or wiredep . My recommendation is to use node-sass instead - if you have no absolute need for ruby-sass of course.
