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，不是现在，安装当我选择“安装”并选择“接受”后，该过程会在一段时间后开始和停止。显示更新服务器上的软件不可用。当我选择“下载Xcode”时，App Store会启动，我可以安装Xcode。似乎还没有安装Xcode，请参阅以下步骤。

安装Xcode后，我启动终端并按照Using Jekyll with pages.

上的说明操作

当我在根文件夹中运行sudo bundle install --verbose时，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)

您必须先安装开发工具。

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

Answer 1

您面临的问题特定于 OSX Mavericks 以及XCode 的最新版本（截至今天，2014年5月21日）。我也是在10.9.2，我也面临以下问题，我相信这也是你所面临的问题。

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

您的输出中某处有Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.。

原因：您的系统上未安装ubiquitus 命令行工具。

解决方案：有三种方法可以安装命令行工具： 1）安装完整的XCode套件，启动它，并让它们出租它会为您安装命令行工具， 2）正在运行xcode-select --install，会弹出一个对话框，询问您是否要安装完整版XCode ，仅安装命令行工具或取消。第二种方法是我做的，它曾经为我工作过一次，但我已经看到它在其他机器上失败了，因为显然它在线查找包的位置有时是可访问的，有时不是，所以试试这个如果你想要，但它可能不起作用，最后 3）从Apple Developer Tools页下载（需要使用Apple帐户登录）
您的输出中某处有clang: error: unknown argument: '-multiply_definedsuppress' [-Wunused-command-line-argument-hard-error-in-future]。

原因： XCode 的最新版本删除了对未使用的命令行参数的支持，如XCode 5.1 release notes mention：


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，除了优化级别标志外，还要使用-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时已经看到了这个问题，其中当前指定了一些无效的编译器选项。

需要更改使用无效编译器选项的项目以删除这些选项。为了帮助简化转换，编译器将暂时接受将错误降级为警告的选项：

-Wno误差=未使用的命令行参数的硬错误功能于将来

注意：将来不再支持此选项。

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原生扩展：

$ ARCHFLAGS = -Wno-error = unused-command-line-argument-hard-error-in-future easy_install ExtensionName

同样，您可以使用以下命令安装Ruby Gem：

$ ARCHFLAGS = -Wno-error = unused-command-line-argument-hard-error-in-future gem install GemName（16214764）

解决方案：上面的XCode发行说明的代码段中提到了解决方案，基本上意味着在运行ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future安装之前设置环境变量gem，如下所示：
```
export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future
gem install <your-desired-gem>
```
...或者，如果您需要将其作为sudo执行，请将以上两行放在脚本中并将其作为sudo执行，或者将其作为sudo内联运行这样：
```
sudo bash -c "export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future; gem install <your-desired-gem>;";
```
注意：上述解决方案（设置ARCHFLAGS环境变量）将在以后的某个时间点停止工作，如上述发行说明中所示。希望到那时，当前 Ruby gems 将从Makefile中删除未使用的命令行选项。

NB：我使用上述方法在 OSX 10.9.2中成功安装github-pages Ruby gem

Answer 2

从App Store安装后，在Applications目录中找到Xcode并启动它（而不是从终端启动）。它可能会告诉你需要下载更多东西。让它。然后，您可以继续按照其他需要Xcode的软件的说明进行操作。如果它仍然无法正常工作，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询问具体细节。祝你好运！
