openstack仪表板显示内部服务器错误

当我试图打开仪表板时，它会显示内部服务器错误。早些时候运行正常，但突然出现了此错误

这是我的apache日志：

如果你在谷歌上搜索这个错误，你会在Launchpad上找到一个带有一长串杂乱无章的注释的页面。最后一条说：

从这里的回答来看，那些遇到这个“bug”的人的根本问题是他们的Horizon安装缺少一些依赖项，而安装该依赖项修复了这个问题

报告的错误“ImportError:无法导入名称库”是加载所有依赖模块失败的症状

因此，原因可能是安装文件不完整或错误

（或可能……未遵循安装说明。）

简而言之，请检查您是否安装了Horizon所有依赖项的正确版本

第二次可能会提供更多的线索

你说：

早些时候运行正常，但突然出现了此错误

这可能是由于应用了更新/修补程序
