I was initially running Python 3.7.0 (manually built/installed) in Raspbian 8.0, on a Raspberry Pi 3 model B. Since the sole purpose of this Pi is to be a print server, I re-flashed it with the more recent Raspbian 9.0, and tried running with the stock Python 3.5.3, but still get the exact same error.
If you need any further information please let me know.
