devstack-Openstack-Pike-Sahara-创build图像时ERROR：venv：命令失败

configuration：在Ubuntu16.04虚拟机上使用devStack的Openstack Pike

插件已启用：

• 撒哈拉
• 热
• 特罗韦
• 撒哈拉仪表板
• Trove仪表板

安装成功，并能够访问地平线。 现在，尝试通过以下步骤为撒哈拉沙漠build立图像：

1. 本地克隆存储库“ https://github.com/openstack/sahara-image-elements ”。
2. 使用tox来构build图像。

当我在/ sahara-image-elements文件夹中运行命令时

• OpenStack在CentOS 6与Ubuntu的
• 理解swiftstack存储
• OpenStack全新安装中的计费模块在哪里？
• 虚拟机器和外部（物理）networking上的虚拟机无法访问互联网
• 无法find任何满足iso8601> = 0.1.9的DevStack下载

stack@devstack:~/sahara-image-elements$ tox -e venv -- sahara-image-create -u 

下面的错误是抛出
