我一直试图在我的Mac上安装rails.我有OS X 10.6.8,我已经确认我有Ruby,版本1.8.7

我跑了sudo gem update并sudo gem update --system获得了该软件的最新版本.

但是,当我运行时,sudo gem install rails我收到此错误:

ERROR:  Error installing rails:
ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h


Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/json-1.6.3 for inspection.

我正在使用 macOS Mojave，当我尝试使用 gem 安装 cocoapods 时，出现以下错误。

构建原生扩展。这可能需要一段时间... 错误：安装 cocoapods 时出错：错误：无法构建 gem 本机扩展。

extconf 失败，退出代码 1

Gem 文件将保留安装在 /Library/Ruby/Gems/2.3.0/gems/ffi-1.12.2 中以供检查。结果记录到 /Library/Ruby/Gems/2.3.0/extensions/universal-darwin-18/2.3.0/ffi-1.12.2/gem_make.out

当我运行以下命令时会出现此错误。

sudo gem install cocoapods

sudo gem install -n /usr/local/bin cocoapods

我已经安装了 xcode 命令行工具，运行时收到以下消息 xcode-select --install

xcode-select: 错误：命令行工具已经安装，使用“软件更新”安装更新

我也同意 xcode 许可协议与命令 sudo xcodebuild -license

错误登录/Library/Ruby/Gems/2.3.0/extensions/universal-darwin-18/2.3.0/ffi-1.12.2/gem_make.out给出了以下内容

当前目录：/Library/Ruby/Gems/2.3.0/gems/ffi-1.12.2/ext/ffi_c /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby -r ./siteco $ mkmf.rb 在 /System/Library/Frameworks/Ruby.fra$ 找不到 ruby​​ 的头文件

extconf 失败，退出代码 1

我该怎么做才能解决这个问题？

自从升级到优胜美地后,我发现此错误试图构建包括ruby.h以下内容的任何内容:
