Question

注意：我的情况几乎与此相同：Can't install pg gem on Mountain Lion。

我刚从Snow Leopard升级到Mountain Lion，Rails给了我各种各样的问题，特别是试图安装'rmagick'宝石。我正在运行Ruby 1.9.3-p362和Rails 3.2.11。

➜  applyco git:(master) ✗ apt-get install libmagick9-dev

我试过了：

使用命令行工具安装Xcode
重新安装自制程序
清除所有repo的宝石（包括Gemfile.lock）并运行bundle install
重新安装bundler gem
重新安装ImageMagick

没有任何东西，包括其他地方的答案，都没有任何用处。你能指出我正确的方向吗？

Answer 1

我遇到了与在Mountain Lion上为RoR 3.2.11设置我的开发环境相同的问题。显然，RMagick（2.13.1）的最后一个版本与最新版本的ImageMagick（6.8.2-0）不能很好地编译。禁用openmp并从源代码构建工作就像是，ahem .. 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brew公式，但这将是下一步尝试。

Answer 2

我在这里遇到同样的问题...... 但有一点不同，也许你的自制软件与另一个版本的Imagemagick相关联。

所以即使没有找到imagemagick-6.8.0-10。

尝试类似的东西 brew unlink imagemagick 然后brew link imagemagick 看看会发生什么。

Answer 3

尝试运行

可能是权限问题

sudo chown -R `whoami` /usr/local

然后再试一次。

Answer 4

我第一次尝试使用Paperclip和Rails 3时遇到了同样的问题。总结以前的答案，对我有用的是：

sudo chown -R `whoami` /usr/local
brew link --overwrite imagemagick

谢谢！
