Question

我已经阅读了很多关于在OS X上安装rmagick gem的问题的帖子，但是没有为MagickCore设置PATH序列的解决方案似乎对我有用。在尝试安装gem时，我不断提出相同的堆栈跟踪。

这是我每次都得到的，而我对如何克服它感到茫然。

我遇到了同样的问题。我需要说的是，我对Ruby，Rails，Homebrew（以及Unix文件结构）都是新手......但是......

我怀疑一旦你解决了PKG_CONFIG_PATH问题，你就会有另一个问题。我会提出一个快速的建议，可能会或可能不适用于第一个，然后解释我为第二个做了什么。

首先，我找到了一个建议，将其添加到.bashrc：PKG_CONFIG_PATH =“/ usr / local / lib / pkgconfig”。我几个小时前做过这件事，它可能为我解决了第一个问题。我不记得了。

其次，我认为imagemagick版本6.8已弃用这些所需的方法：

checking for InitializeMagick() in -lMagickCore... no
checking for InitializeMagick() in -lMagick... no
checking for InitializeMagick() in -lMagick++... no

所以早期的版本仍然会有它们。我按照这里的说明（http://wearepandr.com/blog/article/homebrew-and-installing-old-package-versions）安装了旧版本的软件包。卸载imagemagick后，在/ usr / local / Library / Formula /中运行建议的命令，然后重新安装imagemagick，我就能成功安装rmagick gem。我随机选择了6.7.1-1种。

我真的认为有人应该更新rmagick来反映它的依赖性的变化（它已经陈旧了一两年）。但我自己也不了解这一点。

我建议切换到mini_magick gem。您可以获得ImageMagick提供的所有功能，但安装更容易，内存占用更少。
