Openstack：错误：由于 EnvironmentError 无法安装软件包

Question

我正在尝试在Ubuntu-18.04 LTS上安装Openstack ，而./stack.sh失败并出现以下错误。

尝试pip install setuptools和pip install --force-reinstall --no-deps setuptools==59.6.0但无济于事。

我缺少什么来完成安装？

以下示例显示了使用pip安装 OpenStack 客户端的命令，该命令支持多个服务。

 pip install python-openstackclient

不推荐使用以下单个客户端以支持普通客户端。 我们建议安装和使用 OpenStack 客户端，而不是安装和学习所有这些客户端。 您可能需要安装单个项目的客户端，因为 OpenStack 客户端的覆盖范围还不够。 如果您需要安装单个客户端的项目，请使用下面的列表替换此pip install命令中的PROJECT名称。

 pip install python-PROJECTclient
