INstall fails

Traceback (most recent call last):
File "/home/ken/crowPi-L_BatteryStatus/./batteryStatus.py", line 27, in
bus = smbus.SMBus(1)
FileNotFoundError: [Errno 2] No such file or directory

I also was not able to clone the git, but rather downloaded the zip file??

git clone git@github.com:ppyne/crowPi-L_BatteryStatus.git
