Ruby on rails 无法在redmine中打开项目

当我打开项目时，我看到

500内部错误

在日志文件中，我可以看到下一个信息：

我不懂ruby，所以我根本不知道如何修复它：（

我找到了另一个解决方案，我应该做的就是

rm-rf/var/cache/redmine/default/*

重新启动redmine

另外，多亏了软件包维护人员

我真的不会安装任何关于带有PPA的rails的东西。分配一些时间安装RVM，这将在将来为您省去很多麻烦。@AndrewWei抱歉，我不明白什么是RVM，我如何开始使用它？您能提供更多信息吗？thanks@AndrewWei大多数重要信息：如何摆脱目前的状况？您使用PPA安装Rails和gems…不要。全部删除。将目录更改为Rails项目所在的位置，并始终使用“bundle install”安装gems。您唯一需要的是“Ubuntu”是：ruby和sqlite。让ruby来担心安装所有的gems。嗨，我也有同样的问题，但没有帮助…我没有这个文件夹。
