在mac上失敗的gem install rails錯誤：無法構建gem原生擴展

我下載了xcode，命令行工具，home brew，rvm和ruby，但是當我使用命令sudo gem install rails時，我收到一條錯誤消息。不知道要做什麼幫助會很好，我想在我的新Mac上安裝rails。在mac上失敗的gem install rails錯誤：無法構建gem原生擴展

'gcc --version'的輸出是什麼？ –

配置：--prefix =/Applications/Xcode.app /目錄/ Developer/usr --with-gxx-include-dir =/usr/include/C++/4.2.1 Apple LLVM 5.0版（clang-500.2。 76）（基於LLVM 3.3svn）目標：x86_64-apple-darwin12.5.0 線程模型：posix –

我得到了同樣的錯誤... – christian

你可能不希望被使用sudo與RVM ...嘗試只是：

gem install rails

sudo gcc --version

當你這樣做在Xcode接受用戶協議！（這對我來說是固定的。）
