发送警告: path.join的参数必须是字符串使用-强制才能继续

Question

我试图添加一个复制任务来复制一些js文件。但我得到了跟踪警告和文件停止复制。

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grunt copy -v的结果

关于类似的错误，我已经参考了其他Stackoverflow Question。但是我的GruntJS已经有了Sorhus提到的修复程序。

提前谢谢。

Answer 1

明白了,

dest属性必须是字符串。但不是阵列。

谢谢。
