我在 openSUSE 15.2 上运行 Ussuri 安装。根据官方安装指南，Keystone、Glance 和 Placemente 运行正常，没有任何大问题。但是，当我尝试使用 nova-manage 运行任何命令时，我收到以下消息：
AttributeError: module 'openstack.proxy' has no attribute 'Proxy'
该消息出现在每个带有“nova-manage”的命令中。特别是，我正在执行以下步骤：
填充 nova-api 数据库：
根据官方指南，命令是：
su -s /bin/sh -c "nova-manage api_db sync" nova
每个日志都有该错误，即使是 journalctl -xe 也试图在未填充数据库的情况下启动服务。
其他服务运行良好。
完整日志为：
