提问by john doe
Not sure what happened but when I upgraded to Mavericks it says that Rails it not install. I executed the following command:
不知道发生了什么，但是当我升级到 Mavericks 时，它说它没有安装 Rails。我执行了以下命令：
rails --version
And it said "Rails is not currently installed and run sudo gem install rails".
它说“当前未安装 Rails 并运行 sudo gem install rails”。
I run sudo gem install rails and get the following:
我运行 sudo gem install rails 并得到以下信息：
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.
UPDATE:

You need to install the Command Line Developer Tools. Just open Terminal and type up a command that requires it -- for instance, git, gccor make. Or use the following command:
您需要安装命令行开发工具。只需打开终端并输入需要它的命令 - 例如，git,gcc或make。或者使用以下命令：
$ xcode-select --install
You'll see an alert like this:
你会看到这样的警报：
Just click Install and that's it. As of OS X 10.9, there's no longer need to install Xcodefor Ruby development.
只需单击“安装”即可。从 OS X 10.9 开始，不再需要为 Ruby 开发安装 Xcode。

I had the same problem which I have now been able to solve.
我有同样的问题，我现在已经能够解决。
The problem for me was that I had updated to the latest version of Xcode through the appstore but hadn't actually opened the application to complete the install. So here's what solved it for me:
我的问题是我已经通过 appstore 更新到最新版本的 Xcode，但实际上并没有打开应用程序来完成安装。所以这就是为我解决的问题：
- Updated Xcode
- Opened Xcode application
- Accepted license agreement
- Installed rails
- 更新了 Xcode
- 打开的 Xcode 应用程序
- 接受的许可协议
- 安装导轨
Hope it works for you too.
希望它也适用于你。

It wasn't working for me even when I reinstalled xcode and the command line tools for mavericks.
即使我为小牛重新安装了 xcode 和命令行工具，它也对我不起作用。
But after that, I just did a bundle updateand, for some reason, it worked.
但在那之后，我只是做了一个，bundle update并且由于某种原因，它奏效了。

I think I had the same issues. I updated the xcode and open xcode to accept licence aggrement. Then it worked fine as far as I can remember.
我想我有同样的问题。我更新了 xcode 并打开 xcode 以接受许可协议。然后它工作得很好，据我所知。
