当我尝试打开仪表板时，它会出现内部服务器错误。它之前运行良好，但突然出现此错误。

这是我的 apache 日志：

如果你用谷歌搜索这个错误，你会在 Launchpad 上找到一个错误报告，其中包含一长串杂乱无章的评论。最后一句说：

从这里的回复看来，遇到这个“错误”的人的根本问题是他们的 Horizo​​n 安装缺少一些依赖项，安装该依赖项可以解决问题。

报错“ImportError: cannot import name base”是无法加载所有依赖模块的症状。

因此，原因似乎是安装文档不完整或错误。

（或者可能......未能遵循安装说明。）

简而言之，检查您是否为 Horizo​​n 安装了正确版本的所有依赖项。

第二个错误报告可能会提供更多线索。

你说：

它之前运行良好，但突然出现此错误。

这可能是由于应用了更新/补丁。
