Encountered ModuleNotFoundError: No module named 'natsort' when setting up KVM testbed #3728

Open hsluoyz opened 3 years ago

hsluoyz commented 3 years ago

I'm following this docs: https://github.com/Azure/sonic-mgmt/blob/master/docs/testbed/README.testbed.VsSetup.md#vsonic to setup a testbed. I had an error running:

Error:

It seems that natsort python module needs to be installed, but it's not mentioned in docs: https://github.com/Azure/sonic-mgmt/blob/master/docs/ansible/README.md#installing-ansible-on-ubuntu-14044-lts

Can we improve the docs for it?

Also the Ubuntu 14.04 mentioned in the docs is too old. I'm using Ubuntu 20.04 now. I don't know if there's any difference in the instructions..

Did you run the testbed-cli.sh script inside a sonic-mgmt docker container?

image

If you use the sonic-mgmt docker container to run the testbed-cli.sh tool, there is no need to install dependencies stated in document https://github.com/Azure/sonic-mgmt/blob/master/docs/ansible/README.md#installing-ansible-on-ubuntu-14044-lts which is outdated. The default python environment in the sonic-mgmt docker container is python2. This should be able to temporarily workaround issue #3730
