adafruit_motor_hat's Issues

This module failed to install via pip3

• Adafruit-Motor-Hat version: 0.2.0
• Python version: 3.6.7
• Operating System: Ubuntu 18.04.2 LTS (aarch64)

Description

Install the library to test out my stepper motor. This is running on a NanoPi M4 (RK3399 based) running Armbian 5.7.6

What I Did

# pip3 install adafruit_motor_hat

First error:

Workaround

The resolution was to install each of the dependancies, I feel it would be better if this package called them out or tested for them and exit gracefully than blowing up and expecting consumers to debug it.

# apt install python3-dev
# pip3 install setuptools
# pip3 install wheel

Issues with test run

• Adafruit-Motor-Hat version: Adafruit DC & Stepper Motor HAT for Raspberry Pi - mini Kit - 2348
• Python version: 2.7.13-2
• Operating System: Raspbian GNU/Linux 9

Description

After installing your package via pip install, I performed the test run with the proposed command. I received a traceback which is shown below.

Is the traceback due to false installation issues or HAT issues? Since am quite new in terms of Python programming and GitHub, it could be a beginner problem ;)

Thanks a lot.
