Inky pHat not working- not sure what i did wrong!

So i am trying to just run the basic examples on the inky pHat, heres the traceback:

 Traceback (most recent call last):
  File "", line 29, in <module>
inky_display = InkyPHAT(colour)
  File "/usr/local/lib/python2.7/dist-packages/inky/", line 27, in __init__
  File "/usr/local/lib/python2.7/dist-packages/inky/", line 74, in __init__
self.eeprom = eeprom.read_eeprom()
  File "/usr/local/lib/python2.7/dist-packages/inky/", line 103, in read_eeprom
i2c = SMBus(1)
  File "/usr/local/lib/python2.7/dist-packages/smbus2/", line 279, in __init__
  File "/usr/local/lib/python2.7/dist-packages/smbus2/", line 308, in open
self.fd =, os.O_RDWR)
OSError: [Errno 2] No such file or directory: '/dev/i2c-1'

Try running sudo pip2 install inky from a terminal window.
Then see if the example works
