Devstack安装：运行./stack.sh后n-cpu和q-l3失败

Question

我正在尝试安装DevStack Mitaka：

在执行./stack.sh期间，n-cpu和q-l3服务无法启动。两个屏幕（n-cpu和q-l3）中的错误均显示以下内容：

CRITICAL nova [req-..] TypeError: 'Version object does not support
indexing

类似的问题被标记为已解决，但没有答案（n-cpu failure after running ./stack.sh）

这是错误日志：

有时有助于运行clean.sh并再次运行stack.sh。如果再次发现相同的错误，则需要挖掘日志并将错误发布到此处。
