由于LLDB，尝试运行项目时Xcode崩溃

Question

当我点击“Run”按钮时，无论我的代码如何，Xcode都会立即崩溃。崩溃报告显示LLDB插件无法正确读取：

Error getting value for key 'workerClass' of extension 'Xcode.DebuggerFoundation.Debugger.LLDB' in plug-in 'com.apple.dt.dbg.DebuggerLLDB'

这可能是由于损坏的 LLDB 调试器引起的，只有 Apple 才能解决。 然而，我在互联网上还没有发现很多类似的问题，所以这可能只会出现在我的 Xcode 上。

你尝试重新安装Xcode了吗？ - Nikolai Ruhe

尝试重新安装Xcode。 - Gavin

虽然不是与编程直接相关的内容。 - Nikolai Ruhe

是的，我尝试过重新安装Xcode，但没有起作用。 - Flynamic

一个非常相似的问题（但不完全相同），以及我如何解决它：https://dev59.com/0H7aa4cB1Zd3GeqPo1nt#23327652 - verec

Answer 1

我遇到了同样的问题：无法运行任何Xcode项目。原因是我在Python上玩耍并将其从2.7.x降级到了2.6.8。因此，我将Python更新为2.7.8版本，没有出现问题，Xcode可以非常顺利地部署一切。我尝试过的其他事情甚至包括卸载Xcode并重新安装，但这并没有帮助。这是一个非常有用的页面，可以升级您的Macbook上的Python: http://wolfpaulus.com/jounal/mac/installing_python_osx/。

Answer 2

如果任何人仍然遇到同样的问题，苹果告诉我这是由于安装了错误的“定制”版本Python引起的。我安装了Python 2.7.6并且解决了问题。

Answer 3

这与您的项目无关。某种原因导致您启动的Xcode.app已经损坏。尝试从App Store或ADC下载最新的Xcode。

如果这不起作用，请尝试报告您的问题：Apple Bug Reporter

是的，这是一个相当新的问题，抱歉。 - Vlad Z.

无论如何，还是谢谢你。你知道，最糟糕的问题就是那些你自己解决不了的。 - Flynamic
