Asset res/effects/sjE1.json , Can not create file C:/Users/Yui-re/AppData/Local/SangoSLG/res/effects/sjE1.json.temp: errno 2
lua 调用 cocos2dx 3.5 AssetsManagerEx，有时候能成功，但有时候下载会出现这种错误。求大大们解疑
当下载文件为大小为0字节的时候
Downloader.cpp 647行报错，求解
for (auto it = _progDatas.begin(); it != _progDatas.end(); ++it) {
ProgressData *data = *it;
if (data->downloaded < data->totalToDownload || data->totalToDownload == 0)
{
this->notifyError(ErrorCode::NETWORK, “Unable to download file”, data->customId);
}
else
{
_fileUtils->renameFile(data->path, data->name + TEMP_EXT, data->name);
}
}
