It seems that you changed the template file but forget to run make pkger. Please run make pkger and commit again.

Thanks for the advice, and i think maybe we can use tools like pre-commit to automatical run make pkger to generate the pkg if those template files changed, before commit

That's a good ideal, but it seems git hook only works on local, do you know is there anyway to run it in github server?

Seems github didn't support git hooks, the only we can use is web hooks

Web hook can only do post-check, there is no need to add it since we have unit test to do it (and what I mean is that you should make pkger and push again to pass the unit test)
