基础库：2.11.3 代码：         this.wx.cloud.downloadFile({             fileID: '文件ID', // 文件 ID             success: res => {               // 返回临时文件路径               console.log("Down Load File ID Success");               console.log(res.tempFilePath)             },             fail: res => {                 console.log("Faile");               console.log("Down Load File ID Faile", res);               console.error;             }           }) 真机预览正常，打印“Down Load File ID Success",在微信开发者工具上，没有任何反应，success和fail都没执行. 昨天把微信开发者工具-->本地系统下面的文档做了清理，现在只有一个usr文件夹，在清理前是没有问题的，清理后就成这样了。 该怎么解决？
