openstack仪表板提供内部服务器错误

Question

当我尝试打开仪表板时，它给内部服务器错误。它运行得很好，但突然发生了这个错误。

这里是我的Apache日志：

Answer 1

如果谷歌对于这个错误，你会发现Launchpad上一个bug report，用长散漫评论集。最后一个说：

From the responses here it seems that the root issue with those encountering this "bug" is that their Horizon installation is missing some dependency, and installing that dependency fixes the issue.

The error reported "ImportError: cannot import name base" is a symptom of the failure to load all dependent modules.

The cause therefore would appear to be incomplete or erroneous installation documentation.

（也可能是...未按照安装说明。）

总之，请检查是否已安装了所有的依赖关系地平线的正确版本。

第二个bug report可能会提供更多的线索。

你说：/应用于

It was running fine earlier but suddenly this error occurred.

这可能是由于更新补丁。
