Error calling command 'scan': module 'yaml' has no attribute 'CLoader'

The working environment is Mac OS.

WMDB ≫ scan 1

I also tested on a fresh Kali virtual machine with the same result.

What Python version are you using?

[sdcampbell]

I had the same error on three of my systems:

On my Mac, the Python version is 3.7.4.
On Kali 2019.4, the Python version is 3.7.5.
I also tried the Dockerized version (https://github.com/faun88/WitnessMe) which used 3.7.

I installed WitnessMe as per your instructions using pipenv.

By the way, thanks for the work you put into CrackMapExec and WitnessMe!

@sdcampbell not exactly sure what the issue is here, cause it works for me on Mac. Are you running it in a virtualenv? Can you paste the output of pip freeze here?
Thanks

I am running it in a virtualenv on Mac using pipenv. I installed and ran it using the exact same commands as found in the project's README. Keep in mind that I had the same error after installing it on a fresh Kali 2019.4 virtual machine.
