服务器列表期间的openstackclient python错误

Question

我已经使用以下命令安装了openstackclient，但不知何故得到了奇怪的python错误，并且无法在此处调试出什么问题，希望python专家可以给我一些线索以找出问题所在。

在CentOS 7.6上安装openstackclient（运行python 2.7）

yum -y install epel-release
yum install python-pip
pip install python-openstackclient
pip install -U decorator 

运行openstackclient

我想念您是pip installing的事实，而不是依赖您的软件包管理器。首先，不要这样做：在系统中运行pip install Python库有时会破坏事情。如果要使用pip，则将其安装到不会与系统工具冲突的虚拟环境中。
如果将内容安装到虚拟环境中，则只需删除并重新创建虚拟环境即可。我担心即使我们能够解决more-itertools问题，您也会发现其他问题。
鉴于more_itertools似乎已被某些代码使用，我怀疑简单地删除它会破坏一切。您也许可以显式安装它的早期python 2.x兼容版本。尝试运行：
pip install more-itertools==5.0.0
