openstack儀表板提供內部服務器錯誤

Question

當我嘗試打開儀表板時，它給內部服務器錯誤。它運行得很好，但突然發生了這個錯誤。

這裏是我的Apache日誌：

Answer 1

如果谷歌對於這個錯誤，你會發現Launchpad上一個bug report，用長散漫評論集。最後一個說：

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...未按照安裝說明。）

總之，請檢查是否已安裝了所有的依賴關係地平線的正確版本。

第二個bug report可能會提供更多的線索。

你說：/應用於

It was running fine earlier but suddenly this error occurred.

這可能是由於更新補丁。
