FYI, I'm able to build modmesh and import it in the docker container.

I run the CI locally and the error is due to missingpip3 command.
Looks like pip is not installed correctly in the CI image

Could you please provide a link to the error at your CI run? Image is not helpful in pin-pointing the error.

The nightly CI is healthy: https://github.com/solvcon/modmesh/actions/runs/3028860237 . I would guess the error comes from your change.

I'm using act to run the CI locally.

After inspecting the workflow, that's because I use pyenv on my machine and it's fighting with it.
My PR should not introduce any CI-breaking change after all.
