Why can't I import kmesh's own package?

[lizhencheng]

Please provide an in-depth description of the question you have:
Before I contribute to the kmesh project, I tried to set up the kmesh development environment. When I executed go mod tidy, I encountered the following error.

kmesh.net/kmesh/api/v2/endpoint: cannot find module providing package kmesh.net/kmesh/api/v2/endpoint: unrecognized import path "kmesh.net/kmesh/api/v2/endpoint": reading https://kmesh.net/kmesh/api/v2/endpoint?go-get=1: 404 Not Found

I tried many methods but none of them could resolve it. Do you have any suggestions on how to solve this?
What do you think about this question?:
Maybe there's something I'm not dealing with that's causing this.
Environment:

• Kmesh version:0.1.0

If these steps are specifically required by kmesh, I think they should be aligned with other projects or a guidance document should be provided.

Yes, first you need to generate protobuf with the patch #106
