我在say.py文件中使用 Python SDK 制作了一个简单的程序。Aldebaran Nao 连接到 IP 172.26.96.164 的网络
from naoqi import ALProxy
pr = ALProxy("ALTextToSpeech", "172.26.96.164", 9559)
pr.say("Hello, You are awesome !")
代码运行良好。但是当我在电脑上启动 Naoqi 的本地版本时
> & 'C:\Program Files (x86)\Aldebaran\Choregraphe 1.12.5.3\bin\naoqi-bin.exe'
say.py的代码停止运行并出现以下错误。
PS C:\Users\admin\Desktop\nehchal> python say.py
[INFO ] Starting ALNetwork
[ERROR] Connection failed ! Port 54010 is already in use. Are you already running NaoQi? Use --broker-port option to specify a different port.

有人可以解释一下这个错误到底是什么意思吗?如何知道谁在使用这个端口?如何释放端口或如何使用备用端口?
