升级到Lion（Xcode4.1）后出现“数据模型版本编译错误” [英] "Data Model Version Compile".. error after upgrading to Lion (Xcode4.1)

问题描述

由于昨天升级到Lion（10.6-> 10.7），我无法编译在升级之前没有编译问题的项目。

Since upgrading to Lion yesterday (10.6->10.7), I've been unable to compile a project that had no problems compiling prior to the upgrade.

甚至没有最近更改导致此错误的项目：如果我从SVN退出项目的一个版本从几天或一个星期前，我得到创建时出现同样的错误：

It's not even a recent change to the project that's causing this error: If I checkout from SVN a version of the project from a few days or a week ago, I get the same error whilst building:

命令/开发人员/ usr / bin / momc失败，退出代码6 ，其扩展如下：

进一步说明：

AFAIK，唯一的区别是我现在使用狮子版本的Xcode 4.1（在这之前我使用Xcode 4.1为雪豹）。

Further explanation:

AFAIK, the only difference is that I'm using Lion now, and the Lion version of Xcode 4.1 (where I was using Xcode 4.1 for Snow Leopard prior to this).

我已删除/开发人员/，我重新安装了几次，

I've deleted /Developer/ , I've reinstalled several times, and re-downloaded the App Store Xcode installer too, in case it was corrupt.

如果我创建了一个新 项目使用Xcode（并使用Core Data，我认为这与构建我的项目的任何问题相关），它构建和运行良好：也许有一些我需要做的事来修复我的真正的项目？

If I create a new project using Xcode (and use Core Data, I think that's related to whatever problem there is building my project), it builds and runs fine: maybe there's something I need to do to fix my real project?

任何建议都会辉煌！

Any suggestions would be brilliant! Cheers, Ian

推荐答案

我有同样的问题，OSX Lion 10.7.1， XCode 4.1。

I've had the same issue, OSX Lion 10.7.1, XCode 4.1.

是的，问题可以通过从* .xcdatamodelid目录中删除所有不显示在XCode中的* .xcdatamodel目录来解决。

Yes, the problem is solved simply by removing all *.xcdatamodel directories that are not displayed in XCode from your *.xcdatamodelid directory. These directories appear after *.xcdatamodel renaming in XCode.

删除可以在终端中进行，也可以在Finder中通过显示包内容菜单来完成。

Removing may be done in Terminal or by Show package contents menu in Finder.
