Import error


#1

I am getting an error for both python3 and python2 with raspberry pi 0 and 3

I have tried installing from the git repo and enabled i2c.

i2c doesnt put out anything that is out of the ordinary

I am on retropie. I have tried it on multiple versions of retropie.

the one liner bash script doesnt work. I tried that first.

I am trying to use a scrollphat.

Here is the error:

  File "test-graph.py", line 5, in <module>
    import scrollphat
