pythondev | help | Hey all. I have a question, and I hope this is the right Slack to ask it in. I am trying to get Molecule to work on Windows 7 to test Ansbile roles. I get everything installed, however, when I try and run Molecule, it tells me that sh 1.12.14 is currently not available on Windows, and to install pbs instead. I used pip install pbs, but now I am not sure how to actually get Molecule to use it instead of sh. | 2017-08-31T12:08:30.000093 | Everett | pythondev_help_Everett_2017-08-31T12:08:30.000093 | 1,504,181,310.000093 | 91,610 |
