The reason for the 1 gem installed versus 27 is because the first time you ran it, it seems you installed all of the gems except 1. Only the final gem failed and gave the error Invalid argument - ./ActionDispatch/Routing/Mapper/Scoping/

As for the second and third things you posted, I'm not sure what's going on. Obviously it says there's an issue converting, the error message reads "unable to convert "\x89" from ASCII-8BIT to UTF-8". Again I have no idea what this relates to or why it's happening. Might be worth a google search though.

Can you not continue the lessons, from that first post it seems you have all the gems?
