如何使EventMachine gem在Xcode 4.5.1的OSX Lion 10.8.2上编译 [英] How to get the EventMachine gem to compile on OSX Lion 10.8.2 with Xcode 4.5.1

问题描述

我四处寻找可以找到的解决方案，但似乎找不到解决方案.

I looked everywhere I can find but can't seem to find a solution to this.

我在Lion 10.8.2上使用Xcode 4.5.1，并试图为Rails项目运行bundle，并且它一直在阻塞.我正在为Heroku使用Thin宝石.

I'm using Xcode 4.5.1 on Lion 10.8.2, and am trying to run bundle for a Rails project and it keeps jamming up on this. I'm using the Thin gem for Heroku.

现在我必须没有Thin.有人有解决方案吗?

For now I'm having to do without Thin. Does anyone have a solution?

推荐答案

您必须从 developer.apple.com .

我也遇到了MacOSX10.6.sdk的麻烦，因为那里缺少一些标题，所以我安装了MacOSX10.5.sdk并一切正常.

Also I was having troubles with the MacOSX10.6.sdk because some headers were missing there, so I installed the MacOSX10.5.sdk and all worked fine.
