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

Question

当我从github编译libvirt代码时，出现以下错误：

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

我尝试了一些方法，但没有解决问题

1. pipenv 从 this

   安装 jsonschema==3.0.2

2. 更新 python 版本到 3.8

编译环境： 中心 8； linux 5.14.7; python3.6.8； libvirt 主

Answer 1

尝试更新您的 rst2html5 软件包：

pip install rst2html5

Answer 2

你能试试这个方法吗： 在/usr/local/lib/python3.6/site-packages/rst2html5/init.py文件中 修改为：

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