peewee has recently (Jan 2018) moved to v3.x, and in the process has removed JSONField from playground/kv.py. peewee-2.10.2 (last of the 2.x) works; peewee-3.1.2 (current) does not.
Changing the setup.pyinstall_required to use peewee<3.0 rather than just peewee should (temporarily) solve the problem, but I guess it might be better to figure out what's going on with JSONField going forward ...
