ruby-on-rails - RMagick提示OSX中找不到libMagickCore.5.dylib

Question

运行brew upgrade imagemagick之后，当我运行rails s时，我会得到

/Users/tomi/.rvm/gems/ruby-2.0.0-p247@ezaaa/gems/activesupport-4.0.0/lib/active_support/dependencies.rb:228:in `require': dlopen(/Users/tomi/.rvm/gems/ruby-2.0.0-p247@ezaaa/gems/rmagick-2.13.2/lib/RMagick2.bundle, 9): Library not loaded: /usr/local/lib/libMagickCore.5.dylib (LoadError)
  Referenced from: /Users/tomi/.rvm/gems/ruby-2.0.0-p247@ezaaa/gems/rmagick-2.13.2/lib/RMagick2.bundle
  Reason: image not found - /Users/tomi/.rvm/gems/ruby-2.0.0-p247@ezaaa/gems/rmagick-2.13.2/lib/RMagick2.bundle

我将Carrierwave gem与RMagick一起使用，操作系统是OSX Moutain Lion

Answer 1

目前正在为此奋斗的其他人（2017年1月）-无法使用ImageMagick 7.0.x构建RMagick 2.15.4

首先，请执行以下操作：

brew uninstall ImageMagick
gem uninstall rmagick

其次，请参阅 https://github.com/rmagick/rmagick/issues/256并阅读hristozov的答案，即：

brew rm imagemagick
cd "$(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/"
git checkout 6f014f2b7f1f9e618fd5c0ae9c93befea671f8be imagemagick.rb
brew install imagemagick
brew pin imagemagick
git reset --hard

这将迫使自制软件使用/usr/local/Cellar/imagemagick/6.9.7-3

第三，

gem install rmagick
