[Anthon van der Neut]

This was a result of ruamel.yaml no longer supporting py27 and ruamel.yaml.cmd relying on some compatibility code in the former.
I had already made all the necessary changes in ruamel.yaml.cmd (so it worked for me localy) but forgot to push a new version to pypi.
There is 0.5.7 now on pypi which should have this fixed. Thanks for reporting

[Lucas Cimon]

Thank you!

I confirm that the latest ruamel.yaml.cmd-0.5.7 version works fine for me
