升级到Lion(Xcode4.1)后出现"数据模型版本编译"..错误

Question

自昨天升级到Lion(10.6-> 10.7)以来,我一直无法编译在升级之前编译没有问题的项目.

这个项目最近的变化甚至不会导致这个错误:如果我从几天或一周前从SVN签出一个项目版本,我在构建时会遇到同样的错误:

"Command /Developer/usr/bin/momc failed with exit code 6",扩展到以下内容:

构建错误:

进一步说明:

AFAIK,唯一的区别是我现在正在使用Lion,以及Xcode 4.1的Lion版本(我在此之前使用Xcode 4.1 for Snow Leopard).

我已经删除/ Developer /,我已经重新安装了几次,并且重新下载了App Store Xcode安装程序,以防它已损坏.

如果我使用Xcode 创建一个新项目(并使用Core Data,我认为这与构建我的项目的任何问题有关),它构建并运行良好:也许我需要做些什么来修复我的真实项目？

任何建议都会很精彩!干杯,伊恩

Answer 1

我有同样的问题,OS X Lion 10.7.1,Xcode 4.1.

通过从*.xcdatamodelid目录中删除未在Xcode中显示的所有*.xcdatamodel目录来解决此问题.这些目录出现在Xcode中重命名*.xcdatamodel之后.

删除可以在终端中完成,通过Finder中的"显示包内容"菜单或右键单击Xco​​de中的xcdatamodel并选择"在Finder中显示".
