Ubuntu 14.04 Devstack安装：运行后n-cpu和q-l3失败。/stack.sh

我正在尝试安装DevStack Mitaka：

在./stack.sh执行期间，n-cpu和q-l3服务无法启动。两个屏幕（n-cpu和q-l3）中的错误显示如下：

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

类似问题标记为已解决，但没有答案（）

以下是错误日志：

有时，再次运行clean.sh和stack.sh会有所帮助。如果您再次注意到相同的错误，则需要深入日志并在此处发布错误。

我从头开始运行了两次完整的devstack（Mitaka）安装，结果相同。这似乎与@Anurag Anand报告的情况类似（见上文）。从日志中可以看出，python oslo_util包可能存在问题：u[08-30 10:22:49.975示踪中子[01；35m_[00m文件/usr/local/lib/python2.7/dist packages/oslo_utils/versionutils.py]，第49行，在is_u兼容中[08-30 10:22:49.975示踪中子01；35m_[00m，如果主部件和（请求的_部件[0]！=当前的u部件[0]）：_[10:22:49.975示踪中子[01；35m_U004;[00mTypeError:“版本”对象不支持索引
