Python运行ride.py报错

各位大佬，小白请教一个问题，我在cmd命令下运行ride.py的时候报如下错，能否帮忙看下，小白谢谢各位大佬了~！
E:\Python27\Scripts>python ride.py
Traceback (most recent call last):

错误在最后三句：

File "E:\Python27\lib\site-packages\robotide\publish\publisher.py", line 24, in 
from pubsub import pub
ImportError: cannot import name pub

导入出错了。应该是你的文件导入顺序有误，具体可以参考下面这篇文章检查一下：

出现相同的问题，是未安装Pypubsub导致，pip install Pypubsub安装成功后，问题解决，已实践
