$ rails --version
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.

我成功安装了xcode命令行开发人员工具，然后继续尝试安装rails，它给了我一个像这样的新错误.......

Answer 1

仔细阅读您的输出：

您必须先安装开发工具。

看起来您需要安装OSX开发工具。在Mavericks中执行此操作的最简单方法是运行xcode-select以按照本指南中的说明触发安装：http://www.computersnyou.com/2025/2013/06/install-command-line-tools-in-osx-10-9-mavericks-how-to/

Answer 2

好像你没有在系统中安装XCode。

首先从Mac Store安装XCode（或者只是@DavidUnderwood建议的命令行工具）安装完成后，转到首选项 - ＆gt;下载 - ＆gt;安装命令行工具

还为Mac上的 Rails One Click 找到了有关Rails指南的优秀资源。

请参阅Rackspace中的 step by step guide 。

我遇到了同样的问题...谷歌很多并且终于找到了解决方案

尝试在终端中写这个：

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install rails
