Yesterday I was testing some python code in my raspberry pi 3 (raspbian jessie), it required the package pytz, so I did:
sudo python3 -m pip install pytz
And then this happens:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/pip/basecommand.py", line 122, in main

filename = filename.decode('cp437')
LookupError: unknown encoding: cp437
It's not only with pytz, I tried to update/upgrade/reinstall pip with:
sudo python3 -m pip install -U pip
And the same error happens Any idea about how to solve this problem?
I was searching and trying to solve it yesterday and everything I can do right now is format the SD card.
My Pip version is 1.5.6 but I can't update it, even downloading the code and running setup.py, same problem.
