gulpruby-sass编译到错误的目录

我从这里分叉了github repo，安装了所有东西，但gulp不能正常工作。问题是，如果我在

app.scss

（src风格的文件）中更改了某些内容，那么就不要将其编译为构建文件夹，而是编译为

gulp-ruby-sass: write ../../../../../BicMitchup/AppData/Local/Temp/gulp-ruby-sass/app.css

gulpfile导入了很多不同的文件，这确实是一个很大的问题，但正如我所看到的，问题只出现在

style

task中。下面是此任务的代码

'use strict';

var gulp = require('gulp');
var gulpif = require('gulp-if');
var rename = require('gulp-rename');
var csso = require('gulp-csso');
var autoprefixer = require('gulp-autoprefixer');
var sass = require('gulp-ruby-sass');

var sassOptions = {
    style: 'compressed',
    'sourcemap=none': true
};

function handleError(err) {
    console.log(err.toString());
    this.emit('end');
}

module.exports = gulp.task('styles', function () {
    return gulp.src(config.paths.src.styles)
        .pipe(sass(sassOptions).on('error', handleError))
        .pipe(autoprefixer('last 1 version'))
        .pipe(gulpif(release, csso()))
        .pipe(gulpif(release, rename(config.filenames.release.styles), rename(config.filenames.build.styles)))
        .pipe(gulpif(release, gulp.dest(config.paths.dest.release.styles), gulp.dest(config.paths.dest.build.styles)));
});

我为此花了四个小时，结果脑袋都碎了。没有错误，只是目标文件夹错误。这是包含所有路径的配置文件

global.SRC_FOLDER = 'src';
global.BUILD_FOLDER = 'build';
global.RELEASE_FOLDER = 'release';
global.TMP_FOLDER = 'tmp';

global.config = {

        },
        release: {

            bowerStyles: 'vendor.min.css',

        },
        templates: {
            compiled: 'templates.js',
            angular: {
                moduleName: 'app.templates',
                prefix: '',
                stripPrefix: 'app/'
            }
        }
    },
    ports: {
        staticServer: 1337,
        livereloadServer: 35729
    }
};

红宝石或宝石可能有问题吗？有人能帮忙吗？谢谢
