We're using docker and docker-compose to run our wagtail site.
We've just upgraded to wagtail 1.7 and we're getting an error about the six package conflicting. Error below

And here's dev_requirements.txt
django==1.10.5
wagtail==1.6.3
psycopg2>=2.5.2
django-compressor>=2.1
django-libsass>=0.7
raven==5.3.1
django-cas-client==1.2.0
gunicorn==19.6.0
redis==2.10.5
django-redis-cache==1.6.5
elasticsearch==1.0.0
selenium==2.53.6
pyvirtualdisplay==0.2
flake8==3.2.0
honcho==0.7.1
That works fine, but if I change wagtail==1.6.3 to wagtail==1.7 I get the above six package conflict.
Has anyone run into this or has any idea what could be causing the problem?
It looks like a python module dependency issue, one module is dependent on six 1.5.2 but webencodings needs 1.6.0.
I've tried upgrading pip as well, but that made no difference :-(
I'll try upgrading the the modules I can think of that won't cause an issue.
Any tips or hints greatly appreciated.
The only change to Wagtail's dependencies between 1.6 and 1.7 was to un-pin html5lib from 0.999999 to 'any <1.0 version'. Newer releases of html5lib seem to be more picky about dependencies, but Wagtail should still work happily on the older versions - so I'd suggest adding html5lib==0.999999 to your dev_requirements.txt.
