I will fix this when I go back，is there any other problem?

Your package looks like a great learning resource. I've just started looking at it. I do seem to have a knack at making any software fail. When I find errors/issues/curiosities/etc., how would you like me to report them?

@rickhg12hs Hi, Thanks for your interests, I think the information in your command line is fine. Actually, I recommend downloading the source code directly to get familiar with the source code.
