Libraries are not updated

[Swap-Bot-DUBCC]

I stumbled upon this marvellous piece of work and wanted to try it out since I started living in Sweden and commute to Denmark.
Whenever I try to launch it, it says that I can't import x module from here, and once I do fix that, there's another issue.
I managed to fix most of them without much difficulty, but there is the point where I'm stuck. JSONMixIn, I don't know where to obtain it.
Thank you,
Jonathan
