使用gem安装rails失败

雪城无月 2015-05-09 10:31:21

最近新败了一台mbp，打算学习一下ror，就去安装一些ror的环境来搞一下，然后安装了brew，rvm，使用rvm安装了ruby－1.9.3
结果在使用新安装的gem来安装rails的时候，就悲剧了，死活装不了，这是返回的错误：

Fetching: rack-test-0.6.3.gem (100%)

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.
