设置“xcode-select -switch”后，Xcode停止工作。 [英] Xcode stops working after set "xcode-select -switch"

问题描述

OMG，我做了什么？

几天前，我尝试使用macport安装一些东西，因为我正在使用Xcode 4.3并且当时还没有安装命令行工具， macport无法正常工作。所以我按照一些指南来安装命令行工具，然后使用以下命令：

  sudo xcode-select -switch / Applications / Xcode.app / 
  

我认为除了macport之外的一切都搞砸了：现在，在Xcode，甚至是简单的单视图iOS项目不会被编译，它说未找到UIKit / UIKit.h。

有谁知道如何纠正这个问题？我不想再重新安装巨大的Xcode，今晚要做一些iOS项目，帮忙！

解决方案

你应该将它指向 Developer 目录，而不是Xcode应用程序包。运行：

  sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer 
  

OMG, what I've done?

Couple of days ago, I tried using macport to install something, because I'm using Xcode 4.3 and the command-line tool hadn't been installed by the time, macport wouldn't work. So I followed some guide to get command-line tool installed, then I used following command:

sudo xcode-select -switch /Applications/Xcode.app/

which I think screwed everything except macport: now, in Xcode, even a simple single-view iOS project won't be compiled, it says "UIKit/UIKit.h not found".

Does anyone know how to correct this? I don't want to re-install the gigantic Xcode again, gotta do some iOS project tonight, help!

解决方案

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
