[coaxial]

One temporary fix is to pip install molecule==2.19 ansible==2.7.11.

[seandst]

The latest testinfra is compatible with molecule, and vice versa. molecule is currently using the latest testinfra on master starting with the merge of #2034, and this issue should be fixed with the next release of molecule.
