What version of Python and pickleDB are you using? I was not able to recreate this in my own environment. I recomend using the latest version of pickleDB from the GitHub repo. The PyPI is a little behind.

I am using,

pickleDB==0.8.1 Python==3.5.4

patx commented 5 years ago

I still am unable to re-create the error.

I am using Python 3.7 and also tested Python 2.7 along with pickleDB 0.9.1 which I just made available on PyPI. Please try using the latest pickleDB release and let me know if the error persists.

Once you have upgraded to 0.9.1 if the error is still happening you may want to change

self.db = json.load(open(self.loco, 'rb'))

to

self.db = json.load(open(self.loco, 'rt'))

and see if that fixes your problem. Please let me know the results.
