Ruby test code doesn't run, i2c-devices library problem?

I installed the repo tonight, flashed the firmware, all of it said it was successful.

I updated the script to use D2 since I already had a grove temperature sensor plugged in there, but I'm getting this error:

We're sorry. Ruby was given to us by the community. We don't have anyone on staff that would be Ruby knowledgeable.

We'll have to trust the community for this one.
