升级到Lion，无法构建gem原生扩展 [英] Upgrade to Lion, failed to build gem native extensions

问题描述

不知道我的问题是否与此线程相关（http://stackoverflow.com/questions/6589066/rmagick-and-os-x-lion），但我刚刚升级为Lion;更具体地说，我购买了一台新机器并通过我的旧配置文件迁移。

我无法启动rails 3，因为它找不到rmagick，而且我无法安装rmagick，因为出现以下错误。我尝试卸载rmagick和imageMagick，但尝试捆绑安装时仍然出现相同的错误。有什么想法吗？
谢谢

更新
所以我更新到Xcode4，当我 brew --config 时，它仍然表明我缺少GCC的东西： p>

这怎么可能？

解决方案

看来您需要安装Xcode的Unix开发工具。

当您从Mac App Store安装Xcode时，您可以安装Unix工具： http://itunes.apple.com/us/app/xcode/ id448457090？mt = 12

Not sure if my problem is related to this thread (http://stackoverflow.com/questions/6589066/rmagick-and-os-x-lion), but I just upgraded to Lion; more specifically I purchased an new machine and migrated over my old profile.

I am unable to launch rails 3 because it cannot find rmagick, and I am unable to install rmagick, because I get the following error. I tried uninstalling rmagick and imageMagick, but I still get the same error when attempting to bundle install. Any thoughts? Thank you

UPDATE So I updated to Xcode4 and when I brew --config it still indicates that I am missing GCC stuff:

HOMEBREW_VERSION: 0.8
HEAD: 8368fe489bde47b8f201bfcfdf328944fdf7092b
HOMEBREW_PREFIX: /usr/local
HOMEBREW_CELLAR: /usr/local/Cellar
HOMEBREW_REPOSITORY: /usr/local
HOMEBREW_LIBRARY_PATH: /usr/local/Library/Homebrew
Hardware: quad-core 64-bit sandybridge
OS X: 10.7
Kernel Architecture: x86_64
Ruby: 1.8.7-249
/usr/bin/ruby => /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
Xcode: 
GCC-4.0: N/A 
GCC-4.2: N/A 

How can this be??

解决方案

It appears that you need to install Xcode's Unix Development Tools.

You can install the Unix tools when you install Xcode from the Mac App Store: http://itunes.apple.com/us/app/xcode/id448457090?mt=12
