python - Pyata 模块：连接到 localhost:3000 时出错：[Errno 10061]

Question

我已成功从 svn 签出 pyata 并配置了路径变量。但是现在当我按照教程here中的说明运行example.py时，它给了我这个错误消息：

initializing server.pd...
Error connecting to localhost:3000: [Errno 10061]  No connection could be made because the target machine actively refused it
Traceback (most recent call last):
  File "example.py", line 60, in <module>
    pd.init()
  File "C:\Users\Fredrik\Anaconda\pyata\src\Pd.py", line 37, in init
    self.clear()
  File "C:\Users\Fredrik\Anaconda\pyata\src\Pd.py", line 59, in clear
    self.c.send_pd(Box.canvas + "clear ; ")
  File "C:\Users\Fredrik\Anaconda\pyata\src\communication.py", line 125, in send_pd
    print "Error sending message %s : %s" % (message, err)
NameError: global name 'message' is not defined

产生错误的代码：

#sending a command to pd
def send_pd(self, commands):
    try:
        self.snd_socket.send(commands)
        return True
    except error, err: 
        print "Error sending message %s : %s" % (message, err) 
        return False

有人知道如何解决这个问题吗？
