在调mcpi里面的pollbockhits时出错，哪位知道如何解决？

代码如下：
import mcpi.minecraft as minecraft
import mcpi.block as block

mc = minecraft.Minecraft.create()
events=mc.events.pollBlockHits()

出错信息如下：

Traceback (most recent call last):
File "D:\李畅元编程相关\gitcode\剑球4.py", line 5, in
events=mc.events.pollBlockHits()
File "D:\Python27\lib\mcpi\minecraft.py", line 106, in pollBlockHits
s = self.conn.sendReceive("events.block.hits")
File "D:\Python27\lib\mcpi\connection.py", line 50, in sendReceive
return self.receive()
File "D:\Python27\lib\mcpi\connection.py", line 44, in receive
raise RequestError("%s failed"%self.lastSent.strip())
RequestError: events.block.hits() failed

请问解决了吗

我也遇到了这个问题，全网都没有解决方案。。。。
