Question

任何人都可以看到问题在这里吗？我是python的新手，我需要一些指导。我在带有Lion的Mac上以32位模式运行Python 2.7.3。依赖性包括

pyOSC pyserial 2.6 python-xbee-api 2.00 optparse_gui 0.2 wxPython 2.8

我将不胜感激任何帮助！

Answer 1

使用不在字典中的键进行字典查找时，最常引发KeyError异常。在这种情况下，它看起来就像在最后一行：

self.hive.bees[ nid ].send_output( self.hive.serial, data )

..具体而言，self.hive.bees[ nid ]部分。 nid显然保留0的值，而您的self.hive.bees字典中没有0个字词。

SocketServer.py错误
