As this is just a python wrapper for the library you must first follow the build instructions in the parent directory. When complete, you can build this python wrapper:

  sudo apt-get install python-dev swig
  python ./setup.py build

If you are rebuilding after fetching some updated commits, you might need to remove the build directory first

  rm -rf ./build

If you want to install the library (in a virtualenv or in the system), so that you can import neopixel from anywhere, you need to run:

  python ./setup.py install

Depending on where you are installing, root privileges may be needed (prepend sudo to the install command).

  sudo PYTHONPATH=".:build/lib.linux-armv7l-2.7" python examples/strandtest.py

If you installed the library, there is no need to specify PYTHONPATH:

  sudo python examples/strandtest.py
