path (e.g. /usr/local/lib).
The header files are in /home/pi/go/pkg/mod/github.com/jgarff/rpi_ws281x......
The library (.a) file is in /home/pi/go/pkg/mod/github.com/jgarff/rpi_ws281x.../
Run go get one more time, and it should succeed, but if you still have trouble, cd to /home/pi/rpi_ws281x/
run sudo apt-get install scons
after the installation, from the same folder run scons
now you can change to /home/pi/iot-loop/ and run go get and go build
the executable is located at /home/pi/iot-loop/iotloop
