尝试在OS X上安装Qt时显示“您需要安装Xcode 5.0.0"，但是此版本太旧了，无法使用 [英] Attempt to install Qt on OS X gives 'You need to install Xcode 5.0.0', but this version is so old it's not available
问题描述
我是Windows/Linux开发人员，偶尔为OS X构建程序-尤其是在Qt中.
I am a Windows/Linux developer who occasionally builds for OS X - particularly in Qt.
我有一个在Windows上开发的简单Qt项目.我现在希望在OS X上构建它.
I have a simple Qt project that I have been developing on Windows. I now wish to build it on OS X.
我正在跑步优胜美地.我已经安装了Xcode 7，并且正在尝试安装Qt 5.5.
I am running Yosemite. I have installed Xcode 7 and am attempting to install Qt 5.5.
运行Qt安装程序时，在提示登录到Qt(成功)的提示后，立即收到以下错误消息:
When I run the Qt installer, immediately after the prompt to log in to Qt (which is successful), I receive the following error:
您需要安装Xcode版本5.0.0.
You need to install Xcode version 5.0.0.
我试图在Apple Developer网站上找到Xcode 5.0.0，但这是最新版本的两个主要版本，而且我什至找不到该版本的安装程序.
I have attempted to locate Xcode 5.0.0 on the Apple Developer site, but this is 2 major versions behind the most recent version, and I cannot even find an installer for it.
更重要的是，我确实想知道为什么最新版本的Qt要求Xcode版本被Apple认为太旧了，甚至无法使用.
More to the point, I do wonder why the most recent version of Qt requires a version of Xcode that is considered so old by Apple that it's not even available.
如何克服此问题，以便可以在OS X上安装Qt?
How do I overcome this problem so that I can get Qt installed on OS X?
推荐答案
I ran into the same problem and solved it by following the instructions here. This link describes a similar, but slightly different installer issue.
总而言之，您需要确保Xcode命令行工具已正确安装和设置.我已经安装了它们，但是不得不进入Xcode中的Preferences -> Locations并将下拉列表设置为当前安装的版本.
To summarize, you need to ensure that the Xcode command line tools are installed and set up correctly. I already had them installed, but had to go into Preferences -> Locations in Xcode and set the dropdown to the currently installed version.
该链接显示了Xcode的早期版本，其中路径实际上是Preferences -> Downloads -> Components.
The link shows an earlier version of Xcode where the path is actually Preferences -> Downloads -> Components.
一旦进行了此更改，安装程序将继续成功.
Once I'd made this change, the installer continued successfully.
