Q: I try to run a script and I get an "cannot load such file -- pixelart (LoadError)". Could somebody please help me out getting the script to run?
A: The "cannot load such file -- pixelart (LoadError)" error tells you that you need to install the pixelart package called gems in rubyland.
Try:
$ gem install pixelart
To check all gems (ruby packages) that you have installed locally try:
$ gem list
Now retry running your (ruby) script
