在Mavericks上安装Rails [英] Installing Rails on Mavericks

问题描述

不知道发生了什么，但是当我升级到Mavericks时，它说没有安装Rails.我执行了以下命令:

Not sure what happened but when I upgraded to Mavericks it says that Rails it not install. I executed the following command:

rails --version

它说当前未安装滑轨并运行sudo gem install rails".

And it said "Rails is not currently installed and run sudo gem install rails".

我运行sudo gem install rails并获得以下信息:

I run sudo gem install rails and get the following:

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

    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h


Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/json-1.8.1 for inspection.

更新:

我运行命令gcc --version并得到以下内容:

I ran the command gcc --version and got the following:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/include/c++/4.2.1

推荐答案

您需要安装命令行开发人员工具.只需打开终端并键入需要它的命令-例如git，gcc或make.或使用以下命令:

You need to install the Command Line Developer Tools. Just open Terminal and type up a command that requires it -- for instance, git, gcc or make. Or use the following command:

$ xcode-select --install

您会看到这样的警报:

只需单击安装"即可. 从OS X 10.9开始，不再需要安装Xcode 进行Ruby开发.

Just click Install and that's it. As of OS X 10.9, there's no longer need to install Xcode for Ruby development.
