devstack kilo安装求助，和keystone相关的ImportError

善良超锅锅 2016-07-21 09:31:15

我在虚拟机 Ubuntu 14.04 x64 Desktop中安装OpenStack，用的是devstack，devstack来自code.csdn.net。下载好devstack后切换到stable/kilo分支，运行安装脚本后，遇到了这个import error，重复运行多次都是这个同样的错误。

 from oslo_log import versionutils

 ImportError: cannot import name versionutils

我手动进入到Python交互式环境，发现 from oslo_log import versionutils确实不行，然后我又手动安装了oslo_log。 from oslo_log import versionutils测试可以成功。再次运行安装脚本，还是同样的错误。
再次进入Python交互式环境，发现 from oslo_log import versionutils又不行了。貌似是安装脚本修改了什么。

我在网上搜索了很久，发现没人遇到这个错误。只知道oslo_log和oslo库相关，我对比了一下keystones的requirements和OpenStack的global-requirements，发现它们关于oslo.x的版本依赖并没有冲突。

求助，好几天了，安装devstack都没成功。
