"ImportError: cannot import name 'metadata'" when compile libvirt – CentOS

When I compiling libvirt code from github,There are the following errors:

[395/1071] Generating 'docs/committer-guidelines.html.p/committer-guidelines.html.in'.
FAILED: docs/committer-guidelines.html.p/committer-guidelines.html.in

I have tried some ways,but it didn’t solve the problem

  1. pipenv install jsonschema==3.0.2 from this

  2. update python version to 3.8

Compile Environment:
centos 8; linux 5.14.7; python 3.6.8; libvirt main

    Could you try this method:
    In file of /usr/local/lib/python3.6/site-packages/rst2html5/init.py
    modify to:

    try:
    from importlib import metadata
except ImportError:
    # Running on pre-3.8 Python; use importlib-metadata package
    import importlib_metadata as metadata  # type: ignore
