After following the steps on this page https://github.com/Boeeerb/PiGlow. I did everything correctly and when i try to run the test.py file it says this.

Traceback (most recent call last) : File "test.py" , line 9, in piglow = PiGlow() File "/home/pi/piglow/piglow.py" , line 30,in init IOError: [Errno 2] No such file or directory

I have tried rebooting, and trying it multiple times. I pressed ls and it was there.I dont have twitter so please dont comment about that
