grunt-contrib-copy throw警告:path.join的参数必须是字符串使用--force继续

Question

我正在尝试添加复制任务来复制一些js文件.但我收到警告,文件停止复制.

Running "copy:group1" (copy) task
Warning: Arguments to path.join must be strings Use --force to continue.

Aborted due to warnings.

Gruntfile.js

module.exports = function(grunt) {

    grunt.initConfig({
        copy : {
                group1 : {
            files : [
                {
                        src : ['group1/js/*'],
                        dest : ['lib/group1/js/']
                    }
                ]
            }
        }
    });

    grunt.loadNpmTasks('grunt-contrib-copy');
};

以下是结果 grunt copy -v

我已经提到了类似错误的其他Stackoverflow问题.但是我的GruntJS已经有了Sindre Sorhus提到的解决方案.

提前致谢.

得到它了,

destproperty必须是一个字符串.但不是数组.

谢谢.
