安装Xcode 4.3.1失败（OSX 10.7.3）

已经和这个小时战斗了。我已经从App Store下载了最新的安装程序，希望能够在将设备更新到5.1后再次在设备上运行我的代码。没那么快！我收到一个神秘的错误，说安装失败。这就好像它告诉我“你的安装因失败而失败”。谢谢，上尉明显。安装Xcode 4.3.1失败（OSX 10.7.3）

展望/var/log/install.log我认为这（最后几行的片断失效前）：

我完全相信我的用户名是在sudoers名单上。还有什么我可以错过？我尝试在新的重新启动后安装它，但没有运行，但安装程序。

PS：我还没有尝试删除以前安装的Xcode。我永远不会记得这是必要的，我宁愿继续在模拟器上开发，而不是完全丧失这种能力。

我最近安装了XCode 4.3，它安装干净。我有OSX狮子10.7.2。如果您有以前安装的Xcode版本，则没有什么不同。我正在运行Xcode 4.1,4.2和4.3。可能是下载文件中的错误。 – 2012-03-12 04:36:26

创建一个具有管理权限的新“Admin”用户，并通过该帐户成功安装XCode。多么糟糕的办法让事情能够奏效......我用Windoze安装程序运气更好。显然，我无法自己回答这个问题，持续5个小时。但现在已经解决了。 – 2012-03-12 07:21:09
