Xcode 4.1 无法在我的 Snow Leopard Mac OS X 10.6.3 上安装
我最近下载了 Xcode 4.1 以安装在 Snow Leopard Mac OS X 10.6.3 上，但安装失败。当我单击安装该软件包时，它给我一个“com.apple.installer.pagecontroller error-1”并表示安装失败。有谁知道为什么这可能是问题所在？提前致谢！！ （我已经支付了 99 美元并加入了 Apple 开发）。
I recently downloaded Xcode 4.1 to install on Snow Leopard Mac OS X 10.6.3, however it fails to install. When I clicked to install the package, it gives me a "com.apple.installer.pagecontroller error-1" and says it fails to install. Does anyone know why this might be the problem? Thanks in advance!! (I have paid the $99 and joined Apple development).

原始答案：
Xcode 4.1 仅适用于 Lion，不能在 Snow Leopard 上运行。
对于 Snow Leopard，您必须使用 Xcode 4.0.2。 （或升级到 Lion。）
在 @gcamp 的有用评论后更新：
您如何下载 4.1 ？目前在 App Store 中提供的版本将“Mac OS X 10.7 或更高版本”列为要求，因此它是仅限 Lion 的版本。要获取 Snow Leopard 版本，您必须直接从 iOS 开发中心 下载。
Original answer:
Xcode 4.1 is for Lion only, and won't run on Snow Leopard.
For Snow Leopard, you'll have to use Xcode 4.0.2 instead. (Or upgrade to Lion.)
Update after helpful comment by @gcamp:
How did you download 4.1? The version currently available in the App Store lists "Mac OS X 10.7 or later" as a requirement, so it's the Lion-only version. To get the Snow Leopard version, you have to download it directly from iOS Dev Center.
Xcode 4.1 需要 10.6.7，如自述文件中所述。
您只需更新您的 Mac（并确保您拥有正确版本的 Xcode 4.1）。
Xcode 4.1 requires 10.6.7, as stated in the read me.
You just need to update your Mac (and make sure you have the right version of Xcode 4.1).
X-Code 4 需要 Snow Leopard Mac OS X 10.6.7 或更高版本...请查看 Apple 网站中的自述文件..希望这对您有帮助..
X-Code 4 requires Snow Leopard Mac OS X 10.6.7 or Later...Please check the read me file in Apple website..hope this helps you..
您的安装文件可能已损坏。您尝试过重新下载吗？我知道这是一个相当大的下载，但很可能它在传输过程中被损坏了。
在尝试完全重新下载安装程序之前，请尝试重新启动计算机以查看是否有帮助。
Looks like you may have a corrupted installation file. Have you tried redownloading it? I know it's a rather large download, but it's likely it was corrupted along it's journey.
Before trying a complete re-download of the installer, try rebooting your computer to see if that helps.
