node.js – 使用节点js从ftp站点下载多个文件

ftpClient.ls(".", function(err, res) {
      res.forEach(function(file) {
          console.log(file.name);

            ftpClient.get("./"+file.name, 'D:/styleinc/ftp/'+file.name, function(hadErr) {
                if (hadErr)
                  console.log(hadErr);
                else
                  console.log('File copied successfully!');

      });
    });

但在运行时它给我错误 –

{ [Error: connect ECONNREFUSED]
   code: 'ECONNREFUSED',
   errno: 'ECONNREFUSED',
   syscall: 'connect',
   msg: 'Probably trying a PASV operation while one is in progress' 
  }

我已经成功登录并在ftp网站上验证了自己的身份…..
我不知道该怎么办请指导我.
