在Maverick安裝Ruby中的錯誤

我試過了在這裏發佈的類似問題上提供的多種解決方案，但似乎沒有任何工作。我無法安裝Rails。錯誤消息如下。此外，Wwen我嘗試使用xcode-select --install安裝Xcode，它給我一個安裝網絡cannot download due to network請指教。我對Ruby很新，所以任何幫助將不勝感激。乾杯。在Maverick安裝Ruby中的錯誤

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.

嘗試用自制http://brew.sh，然後安裝蘋果gcc42 – danmanstx 2015-02-09 15:43:31

喜深。謝謝你的幫助。我相信我嘗試過。家庭釀造安裝在我的機器上。 nmacaule-mn1：〜nmacaule $ brew install wget 警告：wget-1.16.1已經安裝。 Brew版本是0.9.5。我如何安裝apple-gcc42？我嘗試了brew install apple-gcc42，但是失敗了。再一次，我對此很新，所以詳細的解釋真的會有幫助。乾杯 – Diversify1281 2015-02-09 19:50:44
