警告:扁平不是一种功能使用--继续使用武力。

Question

我的咕噜声有很奇怪的错误。由于某种原因，在我们的CI系统中运行了一段时间后，这项任务开始失败。可能是面临同样问题的人？

当我运行grunt ：site时，它会输出：

Running "assemble:site" (assemble) task
Warning: flatten is not a function Use --force to continue.

如何修复此错误？任务中的一些配置问题？

Gruntfile.js装配任务部件

module.exports = function(grunt) {
    grunt.initConfig({

        //other tasks
        assemble: {
            options: {
                production: true,
                ext: '.html',
                data: 'src/data/*.json',
                assets: 'dist/assets',
                helpers: 'src/helpers/*-helper.js',
                layoutdir: 'src/templates/layouts',
                partials: ['src/templates/partials/*.hbs']
            },
            site: {
                options: {
                    layout: 'default.hbs'
                },
                files: [{
                    expand: true,
                    cwd: 'src/templates/pages',
                    src: ['*.hbs'],
                    dest: 'dist/'
                }]
            }
        },

        //other tasks

    });

    //other loadNpmTasks

    grunt.loadNpmTasks('grunt-assemble');

    //other registerTask

    grunt.registerTask('build', [
        'concat:bootstrap',
        'concat:js',
        'uglify:js',
        'copy:js',
        'assemble',
        'prettify',
        'sprite',
        'svgmin',
        'sass',
        'postcss',
        'copy:gfx',
        'pngmin'
    ]);
