在小牛上安装地毯宝石

Question

我目前正在尝试为rails项目安装Redcarpet gem。

问题是，前几天我升级到小牛操作系统，我无法安装它，但我不确定它是否与操作系统的变化有任何关系。

这里是我得到的错误：

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

显然有一些C库的一个问题，但是我不知道如何解决它，我一直在谷歌上搜索，但没有发现任何有用的。

任何帮助非常感谢，谢谢！

Answer 1

您是否尝试升级到最新的XCode？

您可能需要运行XCode版本5.0.1才能在Mavericks下编译本机扩展。 Link。

编辑：

由于@Doon在他的评论中指出的那样，你可能需要运行

xcode-select --install 

以获取最新的命令行工具。

Answer 2

您是否尝试删除Gemfile.lock并再次运行软件包安装？

看到这个答案：

Active_Model error in rails

希望这有助于！

Answer 3

好吧我终于发现，当我升级到10.9小牛时，我的gcc坏了，所以我不得不安装命令行工具。

如何做到这一点：

1）打开终端

2）键入 “Xcode中，选择--install”（不带引号）

3）按ENTER

4）点击“安装”

就是这样！
