I'll probably see your document, I execute ruby script/zbout come when you least expect them to script/about no longer exists, please use bin/about instead.

This language because I didn't contact with ruby, so a lot of aspects are not very understand, occasionally see document said again need bin/about but I performed
Error is put forward as follows
The script/about no longer exists, both please use bin/home about
Thank you very much can you help me to solve
