Question

我在设置novadocker时遇到问题，用Openstack设置Docker计算节点。 Openstack版本是Horizon。

我已经按照本教程https://wiki.openstack.org/wiki/Docker#Installing_Docker_for_OpenStack进行了操作，但是当我使用本教程中的内容相应地更改node-compute.conf文件时，当我尝试启动nova-compute时，我在日志文件中收到此错误服务：

ImportError: No module named novadocker.virt.docker

你知道这是什么原因，我该怎么做才能解决它？

非常感谢您的帮助！

/usr/local/lib/python2.7/dist-packages/中的

PS 有一个名为nova-docker.egg-link的文件，其中包含novadocker驱动程序的真实位置......当nova正在寻找时，它似乎被忽略了。

更新

我忘记了python setup.py install。现在我已经完成了但是这是另一个我无法解决的错误：

我不知道这个模块是什么以及如何解决这个问题......

有人能帮助我吗？

我设法通过向后执行最后一次提交来解决这个问题，实际上是这次提交https://github.com/stackforge/nova-docker/commit/9ce916c486a64bfac38fb665fbe7619cef4e1f92。但现在令人惊讶的是我遇到了这个问题：

我其实不知道该怎么办！求你帮帮我。
