This may be caused by a badly installed ruamel-yaml (via distutils). Can you try to delete it and try again?

Yes had to rm /usr/local/bin/anaconda3/lib/python3.7/site-packages/ruamel_yaml-0.15.87-py3.7.egg-info and rm -rf /usr/local/bin/anaconda3/lib/python3.7/site-packages/ruamel_yaml then reinstall worked.
