Ruby on rails 尝试在安装了Xcode（4.3.2）的OS X 10.7上安装Passenger时出现错误：“No No No modHFGen.dll；您必须首先安装开发工具。”；

我试图在安装了Xcode（4.3.2）的OSX10.7上安装Passenger，但这给了我一个错误：“您必须先安装开发工具。”

这对我来说没有意义，为什么它找不到合适的需求呢？我已经从苹果商店安装了Xcode

是否有一个它需要的实际需求列表，而不是这个通用消息？或者有没有一个大家都知道的解决办法，可以帮助我在OSX Lion上与乘客合作？谢谢

嗯，那没用。同样的错误消息，在构建本机扩展时也不能安装精简的类似错误…最终我让它工作了，命令行工具和一些符号链接魔法的组合。。。不管怎样，我会让这个答案成为公认的答案。嗯，那没用。同样的错误消息，在构建本机扩展时也不能安装精简的类似错误…最终我让它工作了，命令行工具和一些符号链接魔法的组合。。。无论如何，我都会让这个答案成为公认的答案。谢谢，我已经通过macek提供的链接安装了它。-注意，它没有解决问题看看这个问题，它可能会有你的答案：我用brew安装了工具，但没有解决问题，gems仍然没有安装，我必须重新安装rubies吗？谢谢，我已经安装了，从macek提供的链接注意，它没有解决问题看看这个问题，它可能会有你的答案：我用brew安装了工具，但没有解决问题，gems仍然没有安装，我需要重新安装吗
