Hi, It's not just the pinout script, the library is non-functional without pkg- resources installed:
$ python3 -c "import gpiozero" Traceback (most recent call last): File "<string>", line 1, in <module> File "/usr/lib/python3/dist-packages/gpiozero/__init__.py", line 22, in <module> from .devices import ( File "/usr/lib/python3/dist-packages/gpiozero/devices.py", line 19, in <module> import pkg_resources ModuleNotFoundError: No module named 'pkg_resources' Installing python3-pkg-resources fixes this example. -Kipp
