ruby-on-rails-3 - 无法在 Mountain Lion 上安装 rmagick gem

Question

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，尤其是在尝试安装“rmagick”gem 时。我正在运行 Ruby 1.9.3-p362 和 Rails 3.2.11。

我试过:

• 使用命令行工具安装 Xcode
• 重新安装自制软件
• 清除我所有的 repo 的 gem(包括 Gemfile.lock)并运行 bundle install
• 重新安装 bundler gem
• 重新安装 ImageMagick

没有任何用处，包括 SO 其他地方的答案。你能给我指出正确的方向吗？

Answer 1

我在为 RoR 3.2.11 在 Mountain Lion 上设置我的开发环境时遇到了同样的问题。显然，最新版本的 RMagick (2.13.1) 不能很好地与最新版本的 ImageMagick (6.8.2-0) 一起编译。禁用 openmp 并从源代码构建就像，啊哈.. Magick。

brew uninstall imagemagick
brew install imagemagick --disable-openmp --build-from-source
gem install rmagick

我不需要编辑 http://blog.paulopoiati.com/2013/01/28/installing-rmagick-in-mac-os-x-mountain-lion-with-homebrew/ 中描述的冲泡配方，但这将是下一步的尝试。
