ruby-on-rails - 在 macOS 上安装 rmagick 不起作用，未找到重复引用和引用

Question

我正在尝试在 MacOSX 上安装 rmagick，但由于某种原因，我在安装时遇到了很多问题。 我发现像:this thread和 this other thread ，但不起作用，看起来如果我有 2 个对 rmagick 的引用，并且文件 wand/MagickWand.h 不是由 gem 创建的。

我的环境变量是:

$ echo "$PKG_CONFIG_PATH"
/usr/local/Cellar/imagemagick/6.8.9-1/include/ImageMagick-6/

我尝试安装gem时的日志是:

$ gem install rmagick

我的一个 friend 在升级到mavericks时也遇到了同样的问题，如果你使用的是brew，请尝试卸载该软件包并重新安装。

brew rm imagemagick

brew update && brew upgrade

和

brew reinstall imagemagick
