[LayaAirIDE3]命令行打包图集

想请问一下官方看到插件里面有个
IEditorEnv.TexturePacker.pack这个接口。这个是可以给文件夹打包成图集的吗？
写了一个测试了。代码如下：

static async texturePacker() {

        const src = [

            "E:/work/client/trunk/client/mxdzz_client/assets/res/atlas/equip/1011/jineng_0.png",

            "E:/work/client/trunk/client/mxdzz_client/assets/res/atlas/equip/1011/jineng_1.png",

            "E:/work/client/trunk/client/mxdzz_client/assets/res/atlas/equip/1011/jineng_2.png",

            "E:/work/client/trunk/client/mxdzz_client/assets/res/atlas/equip/1011/jineng_3.png",

        ]

        const outDir = "E:/work/client/trunk/client/mxdzz_client/assets/res/atlas/equip"

        return IEditorEnv.TexturePacker.pack(src, outDir)

    }

但是运行并没有效果。运行结果如下


希望官方指点一下。是哪里出了问题。
如果这个不是命令行打包图集的方法。请问官方是否有方法可以通过命令行打包图集？
