Xamarin Studio Error: A valid Xcode installation could not be found
提问by duDE
I updated Xcode this morning (version 4.6.2) and right now, I cannot compile my projects.
我今天早上更新了 Xcode（版本 4.6.2），现在我无法编译我的项目。
Error: A valid Xcode installation could not be found. If your copy of Xcode is installed to a non-standard prefix, please specify the location in Xamarin Studio's Preferences under 'SDK Locations'
错误：找不到有效的 Xcode 安装。如果您的 Xcode 副本安装到非标准前缀，请在“SDK 位置”下的 Xamarin Studio 首选项中指定位置
I checked that SDK Locations are good but still same problem.
我检查了 SDK Locations 是好的，但仍然是同样的问题。
Any ideas to solve this problem ? Xamarin Studio 4.0.3 (Build 13)
任何想法来解决这个问题？Xamarin Studio 4.0.3（内部版本 13）

OK, it seems to be the Bug of Xcode 4.6.2: http://forums.xamarin.com/discussion/comment/10620/#Comment_10620
好吧，看来是Xcode 4.6.2的Bug：http: //forums.xamarin.com/discussion/comment/10620/#Comment_10620
There is a known issue with Xcode 4.6.2, we would recommend that you re-download Xcode 4.6.1 and continue using that until we get a fix out for Xamarin Studio. You can re-download Xcode 4.6.1 from https://developer.apple.com/downloads/index.action
Xcode 4.6.2 存在一个已知问题，我们建议您重新下载 Xcode 4.6.1 并继续使用它，直到我们为 Xamarin Studio 找到修复程序。您可以从https://developer.apple.com/downloads/index.action重新下载 Xcode 4.6.1
The only one way is to go back to 4.6.1 :(
唯一的方法是回到 4.6.1 :(

You just need to be registered as Apple developer and will find previous version on Developer Tools

Do you have to have a paid developeraccount to get the 4.6.1 version of xcode from apple? I only have the free account and I haven't found it on the apple hp.
是否必须有付费的开发者帐户才能从苹果获得 4.6.1 版本的 xcode？我只有免费账号，在apple hp上没找到。
