Metaclasses conflict

I'm consistently getting a TypeError exception:

It happens both in my machine and with your docker image that I had to modify to install make so pip could build deps:

RUN apk add --no-cache \
gcc \
musl-dev \
libffi-dev \
openssl-dev \
make

Did you get it working? If so, can you send me a pull request?

I couldn't get it working and after not so long found the jwcrypto library to export my JWKS's public key to PEM format. Right now I can't devote time on it, sorry!

Got the same issue. Works for me after pip install six==1.10.0
