使用rvm和brew在Mac OS X上安装hpricot
在 Mac OS X 上安装 hpricot 时遇到问题。我怀疑这可能是 rvm 和brew 之间的问题？
RVM 1.0.5 酿造 0.7
有什么想法？建议？谢谢！

Having problems installing hpricot on Mac OS X. I suspect it might be an issue between rvm and brew?

错误：无法构建 gem 本机扩展。和检查 stdio.h... 否是可疑的。 Hpricot 与许多其他 Ruby gem 一样，需要编译一些代码，如果缺少开发包，就会失败。您正在运行 RVM，并且 1.8.7 位于您计算机上的 ~/.rvm 中，因此看起来是因为 RVM 必须编译 Ruby，但失败听起来似乎并非如此。你是否在 /Developer 目录中安装了 Apple 的 XCode？如果您没有安装它和/或目录不存在，您可以在 MacOS 安装光盘上或 Apple 的开发人员站点上找到安装程序：http://developer.apple.com/technologies/xcode.html
除此之外，我建议使用 Nokogiri 而不是 Hpricot。不久前，我在 Hpricot 中遇到了几个错误，导致它无法满足我的需求，因此转而使用 Nokogiri。您会发现这两个 gem 具有相似的语法。 http://nokogiri.org/
ERROR: Failed to build gem native extension.andchecking for stdio.h... noare suspicious. Hpricot, along with many other Ruby gems, needs to compile some code and will fail if the development package is missing.You are running RVM and 1.8.7 is in ~/.rvm on your machine, so it looks like it is because RVM would have to compile Ruby, but the failure sounds like it isn't. Do you have Apple's XCode installed in the /Developer directory? If you didn't install it and/or the directory isn't there, you can find the installer on your MacOS install discs, or at Apple's Developer site: http://developer.apple.com/technologies/xcode.html
That aside, I'd recommend using Nokogiri over Hpricot. I ran into several bugs in Hpricot a while back that made it unusable for my needs, and switched to Nokogiri. You'll find the two gems have similar syntax. http://nokogiri.org/
事实证明这是 XCode 版本依赖性。将 XCode 更新到 3.2.4 解决了这个问题。
Turns out this was an XCode version dependency. Updating XCode to 3.2.4 resolved this.
