catkin build error: redefinition of 'struct i2c_msg'

[xiangee2022]

When I run the "catkin build" command, the following error occurs, what is the cause? How to solve? Any help from you will be appreciated!

I found that removing the ubiquity_motor directory under the src directory can compile and pass. But I don't know if this will have any side effects.
