Xcode 因 SourceCache 中的断言失败而崩溃

Xcode Crashes with Assertion Failure in SourceCache

提问by Tushar Vengurlekar

I am getting following error when I try to edit any file in my project.

当我尝试编辑项目中的任何文件时出现以下错误。

I tried clearing XCode cache as mentioned in thisquestion, but that didn't work. I tried reinstalling xcode but that also failed.

我尝试清除此问题中提到的 XCode 缓存，但这没有用。我尝试重新安装 xcode，但也失败了。

I am using Xcode Version 4.2.1 on MAC OSX Version 10.7.2 (Lion).

我在 MAC OSX 版本 10.7.2 (Lion) 上使用 Xcode 版本 4.2.1。

Let me know if you have any suggestions regarding the same.

如果您对此有任何建议，请告诉我。

Thanks.

谢谢。

This is solved now. This was due to missing repository in XCode. I had to go to Organizer -> Repositories and press + button in bottom left corner to add repository. After which my project is compiling very well. Thanks Horst for your effort though.

现在已经解决了。这是由于 XCode 中缺少存储库。我必须去 Organizer -> Repositories 然后按左下角的 + 按钮来添加存储库。之后我的项目编译得很好。不过感谢霍斯特的努力。

Read-only source/plist/project files had been the root cause for the same problem with my Xcode. You may just verify that all files in your project folder are writable.

只读源/plist/项目文件是我的 Xcode 出现同样问题的根本原因。您可以验证项目文件夹中的所有文件是否可写。
