Ah it looks like it can't find any /dev/i2c* devices--double check I2C is enabled on the Raspberry Pi. Check this page for details on the kernel module to enable: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-4-gpio-setup/configuring-i2c In particular run raspi-config to enable the I2C device tree parameter, then manually edit /etc/modules to make sure the right I2C drivers are loaded, and finally use the i2cdetect command to double check you can see a device on the I2C bus. Give that a shot and let me know if you still see issues, thanks!
