On a new installation of Raspbian I did:

Enabled I2C in raspi-config
Create a python test file containing just the two imports at the top of your file
Ran my test file with python3 -> gave the same import error you get
Installed Adafruit_GPIO with: pip3 install AdaFruit_GPIO
Ran my test file again -> succeeded with no errors

So from this is does look like your system is to blame. So reinstalling Rasbian will work.

To install dependencies for Python 3 on Raspberry Pi, this need to be executed: sudo python3 -m pip install git+git://github.com/chrisb2/pi_ina219.git this fixes the import error above.
