Good news, it's not your error. I've put a bug report in.

The workaround is to;
 * 1) Install git
 * 2) Add it to your system's PATH
 * 3) run git clone --recursive https://gerrit.wikimedia.org/r/pywikibot/compat.git into some directory

But if you're not comfortable doing that, I might have another solution soon
