Description

I'm having trouble installing. Maybe someone has gotten past this. When running sudo python -m amazon.dash install things fail. Immediately I get a ps: illegal option error:

Executing all install scripts for Amazon-Dash
[OK] config has been installed successfully

removing '--no-headers' as an argument for the ps command in the init.py file resolved this error for me.

Solved in the development version.
