Failed to discover chaostoolkit-kubernetes

[Xat59]

First, I've successfully installed chaostoolkit and chaostoolkit-kubernetes from pip in my venv :

⇒  python3 -m venv chaostk
⇒  source chaostk/bin/activate
⇒  pip install chaostoolkit
⇒  pip install chaostoolkit-kubernetes

I am trying to use chaostoolkit-kubernetes on my k8s cluster, but I always get the following errors :

⇒  which chaos
~/venv/chaostk/bin/chaos
⇒  chaos --verbose discover chaostoolkit-kubernetes

I also tried to run chaos discover chaostoolkit-aws that works well.

Thanks for the support.

Actually, after the installation of chaostoolkit-kubernetes pip package, I have closed the terminal. Then retried the discover command and it works.
