我通过rbenv安装ruby 2.2.3并安装rails 4.2.1

当我想通过rails -v在终端中查看rails版本时显示：

Ignoring json-1.8.2 because its extensions are not built.  Try: gem pristine json --version 1.8.2
Ignoring json-1.8.3 because its extensions are not built.  Try: gem pristine json --version 1.8.3
Ignoring nokogiri-1.6.6.2 because its extensions are not built.  Try: gem pristine nokogiri --version 1.6.6.2
Rails 4.2.1

或通过rails new app创建新应用程序告诉我：

Ignoring json-1.8.2 because its extensions are not built.  Try: gem pristine json --version 1.8.2
Ignoring json-1.8.3 because its extensions are not built.  Try: gem pristine json --version 1.8.3

The file "/usr/include/iconv.h" is missing in your build environment,
which means you haven't installed Xcode Command Line Tools properly.

To install Command Line Tools, try running `xcode-select --install` on
terminal and follow the instructions.  If it fails, open Xcode.app,
select from the menu "Xcode" - "Open Developer Tool" - "More Developer
Tools" to open the developer site, download the installer for your OS
version and run it.

当我尝试运行例如gem pristine json --version 1.8.2向我显示错误！我该如何解决这个问题？

答案 0 :(得分：4)

我遇到了同样的问题，我是一名mac用户。目前尚不清楚你是否也是一个mac用户，但在这里我解释了我是如何修复的，因为我注意到最近的Xcode自动更新命令行工具。

一段时间后打开Xcode，它提示我下面的屏幕：

Xcode popup screen

单击“安装”后，安装组件需要一段时间：

Xcode installing components

然后我所要做的就是运行你上面提到的建议gem pristine ...命令，所有命令都恢复正常。
