After completing the compilation of cpprestsdk and etcd-cpp-apiv3, execute

The following error occurs
Do I need to lower the python version, or lower the cmake version, or what should I do?

The pybind requires PyFrameObject, which was removed in python 3.11 (https://github.com/pybind/pybind11/discussions/4333). A workaround is to downgrade python version of (base) to 3.10, or build pybind by source code.

Which source code should I compile 3.10 based on? Whether I can compile it through the source code corresponding to Mooncake. Is there any method or reference link?

You can try use pip install to install correct version instead of apt install. See Pybind11 Install Guide

I fixed this by cloning pybind11 repo and:

cd pybind11
mkdir -p build
cd build
cmake ..
make -j && make install

Thanks, I completed the installation and compilation of the third-party library and mooncake by installing python 3.10.8, which avoided the above version problem. At the same time, I also cloned the pybind11 v2.13.6 repo and installed and compiled it, thus solving the previous python 3.11 issue.

It would be great to add python 3.12 support
