Xcode无法安装在OSX 10.9.2上

Question

使用OS X 10.9.2 Mavericks

我在安装github-pages gem时遇到了麻烦。 我需要先安装Xcode，但这会导致错误。 我尝试使用以下命令安装Xcode： xcode-select --install 。 该对话框显示三个选项：“下载Xcode”，“不立即安装”，“安装”当我选择“安装”并选择“接受”后，该过程开始并在一段时间后停止。 显示该软件在更新服务器上不可用。 当我选择“下载Xcode”时，App Store启动，我可以安装Xcode。 仍然似乎未安装Xcode，请参阅以下步骤。

安装Xcode后，我启动终端并按照与页面一起使用Jekyll上的说明进行操作。

当我在根文件夹中运行sudo bundle install --verbose ，编译器会生成error:/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/mkmf.rb:430:in 'try_do': The compiler failed to generate an executable file. (RuntimeError) error:/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/mkmf.rb:430:in 'try_do': The compiler failed to generate an executable file. (RuntimeError)

您必须先安装开发工具。

Below the output of the `sudo bundle install` command:

您面临的问题特定于OSX Mavericks和最新版本的XCode （截至今天，2014年5月21日） 。 我也在10.9.2上，并且我遇到了以下问题，我相信这也是您面临的问题。

以下是我在尝试安装/构建Ruby gem时遇到的问题，这些问题涉及编译本机代码和/或某些依赖的依赖项：

• Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.您得到类似Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. 在输出中的某处。

  原因：您的系统上未安装ubiquitus 命令行工具 。

  解决方案：有3种安装命令行工具的方法 ： 1）安装完整的XCode套件，启动它，然后让它为您安装命令行工具 ， 2）运行xcode-select --install ，将弹出一个对话框，询问您是否要安装完整的XCode ， 仅安装命令行工具或“ 取消” 。 第二种方法是我所做的，并且对我有用一次，但是我发现它在其他机器上失败了，因为有时可以访问（有时无法访问）在线查找软件包的位置，因此请尝试尝试此操作，但它可能无法正常运行，最后3）从Web上的Apple Developer Tools页面下载（需要使用Apple帐户登录）

• 您会在输出中的某处得到类似clang: error: unknown argument: '-multiply_definedsuppress' [-Wunused-command-line-argument-hard-error-in-future] 。

  原因：最新版本的XCode删除了对未使用的命令行参数的支持，因为XCode 5.1发行说明提到 ：

  编译器

  从Apple LLVM编译器版本5.1（clang-502）及更高版本开始，优化级别-O4不再意味着链接时间优化（LTO）。 为了使用LTO进行构建，除了优化级别标志之外，还明确使用-flto选项。 （15633276）

  Xcode 5.1中的Apple LLVM编译器将无法识别的命令行选项视为错误。 在构建Python本机扩展和Ruby Gems（其中当前指定了一些无效的编译器选项）时，已经看到了此问题。

  使用无效的编译器选项的项目将需要更改以删除这些选项。 为了帮助简化过渡，编译器将临时接受一个选项，将错误降级为警告：

  -Wno误差=未使用的命令行参数的硬错误功能于未来

  注意：将来将不再支持此选项。

  要解决此问题，请设置ARCHFLAGS环境变量以将错误降级为警告。 例如，您可以使用以下命令安装Python本机扩展：

  $ ARCHFLAGS = -Wno-error =未使用的命令行参数-将来的硬错误easy_install ExtensionName

  同样，您可以使用以下命令安装Ruby Gem：

  $ ARCHFLAGS = -Wno-error =未使用的命令行参数-将来的错误错误gem install GemName（16214764）

  解决方案：上面的XCode发行说明的摘录中提到了该解决方案，并且基本上意味着在运行gem install之前设置环境变量ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future ，像这样：

   export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install <your-desired-gem> 

  ...或者，如果您需要以sudo身份执行它，请将上述两行放在脚本中并以sudo身份执行，或者以sudo inline的形式运行，如下所示：

   sudo bash -c "export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future; gem install <your-desired-gem>;"; 

  注意：如上述发行说明所述，上述解决方案（设置ARCHFLAGS环境变量）将在将来的某个时候停止工作。 希望到那时，当前的Ruby gems将从其Makefile删除未使用的命令行选项。

注意：我使用上面概述的方法在OSX 10.9.2中成功安装了github-pages Ruby gem 。

Answer 2

从App Store安装后，请在Applications目录中找到Xcode并启动它（而不是从终端启动）。 它可能会告诉您它需要下载更多内容。 让它。 然后，您可以继续进行操作，并按照需要Xcode的其他软件的说明进行操作。 如果仍然无法正常运行，则可能是其他软件的安装说明存在问题。 我会联系该软件的维护者以询问详细信息。 祝好运！
