Question

我正在尝试在我的OS X Mountain Lion上安装ffi gem（因此我可以运行Octopress）并且遇到错误。

运行gem install install ffi -v '1.0.11'会得到以下输出：

/chetanshenoy.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb

感谢任何帮助。

看起来ffi gem也不喜欢路径中的空格，因为你在config已经检查过它不是使用这条路径的ruby，必须是编译gem的过程中的东西

要使它编译你需要摆脱空格，有几种方法：

在没有空格的路径中重新安装rvm，首先您需要更改rvm_path中的~/.rvmrc位置，这是“安全”的选择，
将rvm直接移动到rvm_path指向的路径 - sudo rm -rf /chetanshenoy.rvm && sudo mv "/Volumes/Secondary - HDD/Users/chetanshenoy/.rvm" /chetanshenoy.rvm - 这应该可以工作，因为ruby没有主目录的记录，但是不能确定带有空格的路径是否保存在任何路径中位置 - 如果出现问题，请使用解决方案1。

正如Issue with installing ImageMagick and rmagick on Mountain Lion中所述，ffi似乎已配置为查找“gcc-4.2”，因此，一旦我更新了Apple command line tools（我可能需要或可能不需要这样做），我创建了一个符号链接，使ffi安装配置更加快乐：

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
