python-3.x - Devstack 安装 - “错误：命令错误，退出状态为 1”

问题描述

我正在尝试根据本教程在 Ubuntu 18.04 上安装 Devstack 。我创建了具有以下内容的用户stack和文件：local.conf

[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

当我运行时./stack，我收到以下错误：

解决方案

由于该错误与enumPython lib ( ) 有关，因此我在这个问题AttributeError: module 'enum' has no attribute 'IntFlag'中遵循了Haken-lid的建议，它对我有用：

pip uninstall -y enum34
