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.

Already fixed with #14831

The root cause with your issue stems from a dependency management conflict between two software ecosystems. According to the error message, your 'markupsafe' was installed using 'pip' at the path /usr/local/lib/python3.8/dist-packages/markupsafe. The 'jinja2' that depends on it was installed using 'apt' at the path /usr/lib/python3/dist-packages/jinja2. The versions of the two are not compatible. In fact, there is a version of 'markupsafe' in the system that 'jinja2' correctly depends on, but the Python interpreter prioritizes the 'markupsafe' installed by 'pip', leading to this issue. There are typically two solutions to this problem: (1) Use 'pip' to uninstall markupsafe, and then reinstall it using 'apt', or uninstall 'jinja2' using 'apt' and reinstall it using 'pip'. (2) Use Python's imp module to customize the path and import the 'markupsafe' from the 'apt' path before importing 'jinja2'. An example is as follows:

import imp
path = ['/usr/lib/python3/dist-packages']
fp, pathname, description = imp.find_module('markupsafe', path)
imp.load_module("markupsafe", fp, pathname, description)

Hope my diagnosis is helpful to you！ @AS132933
