编译 libvirt 时"ImportError: cannot import name 'metadata'"

Question

当我从github编译libvirt代码时，有以下错误:

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

我试了几种方法，但都解决不了问题

1. pipenv安装jsonschema = = 3.0.2从这个

2. 更新python版本到3.8

编译环境:centos 8;linux 5.14.7;python 3.6.8;libvirt主要

你可以试试这个方法吗?/usr/local/lib/python3.6/site-packages/rst2html5/init. py修改:

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