I solved the problem by updating libyang to v2.0.0 to v2.1.80.

If you are using Ubuntu, please check following lines in docker/ubuntu-ci/Dockerfile. You can find that libyang version is updated:

# build and install libyang2
RUN cd && pwd && ls -al && \
    git clone https://github.com/CESNET/libyang.git && \
    cd libyang && \
    git checkout v2.1.80 && \
    mkdir build; cd build && \
    cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr \
          -DCMAKE_BUILD_TYPE:String="Release" .. && \
    make -j $(nproc) && \
    sudo make install

Looks like required python dependencies are not installed in your environment.
According to your error message, you may try to reintsall python3-dev and python3-sphinx.

If you are using ubuntu and contunue to encounter new dependency problems, you can follow commands in docker/ubuntu-ci/Dockerfile to install or update dependencies. Please install all dependencies according to the Dockerfile first.
