【问题描述】：
注意：我的情况几乎与此相同：Can't install pg gem on Mountain Lion。
我刚刚从 Snow Leopard 升级到 Mountain Lion，Rails 给我带来了各种各样的问题，尤其是尝试安装“rmagick”gem。我正在运行 Ruby 1.9.3-p362 和 Rails 3.2.11。

➜ applyco git:(master) ✗ brew install imagemagick --disable-openmp

Error: imagemagick-6.8.0-10 already installed
➜ applyco git:(master) ✗ apt-get install libmagick9-dev

我试过了：
- 使用命令行工具安装 Xcode
- 重新安装自制软件
- 清除我所有 repo 的 gem（包括 Gemfile.lock）并运行
bundle install - 重新安装捆绑器 gem
- 重新安装 ImageMagick
没有任何用处，包括 SO 上其他地方的答案。你能指出我正确的方向吗？

我在这里遇到了同样的问题......但有一个区别，也许你的自制软件链接到另一个版本的 Imagemagick。因此，即使安装了 imagemagick-6.8.0-10 也找不到。尝试类似
brew unlink imagemagick然后brew link imagemagick看看会发生什么。你试过brew doctor吗？
