That's found in the stix2 module - but you should get that if you install pycti. It's in requirements.txt. Probably worth running the snippet from the docs - just to make sure you're not missing other requirements:
for I in $(find Cortex-Analyzers -name 'requirements.txt'); do sudo -H pip2 install -r $I; done && \ for I in $(find Cortex-Analyzers -name 'requirements.txt'); do sudo -H pip3 install -r $I || true; done

Six is already installed in cortex machine but is in a old release.. you need to update it. We added a minimal six release as requirements in develop branch

Ok, I fixed the problem... I also had to switch to the "develop" branch for the OpenCTI responder...
