merb datamapper 似乎已损坏。

有人知道如何解决这个问题吗？
我刚刚卸载了 merb 并再次安装了它，但仍然收到此错误。

尝试升级到几天前刚刚发布的 Merb 1.0.15。它增加了对新 DataMapper 系列的支持并解决了这个特定问题。
我相信 gems 现在位于 gemcutter 上，因此您应该遵循以下安装说明：

Try upgrading to Merb 1.0.15, which was just released a few days ago. It adds support for the new DataMapper series and resolves this specific issue.
I believe the gems are on gemcutter now, so you should probably follow these installation instructions:
