如何在OS安裝rmagic 2.13.1和ImageMagick的X 10.8.2

Question

我已經在越來越安裝在OS X，但沒有一個解決方案，用於設置PATH veriables爲rmagick寶石看了很多帖子，似乎有問題MagickCore似乎爲我工作。試圖安裝gem時，我一直提供相同的堆棧跟蹤。

這是我每次都會得到的，而且我對如何克服這個問題感到不知所措。

我遇到同樣的問題。我需要說的是，雖然我對Ruby，Rails，Homebrew（是的Unix文件結構）非常陌生......但是...

我懷疑一旦你解決了PKG_CONFIG_PATH問題，你將擁有另一個。我會提出一個快速建議，可能會或可能不適用於第一個，然後解釋我爲第二個做了什麼。

首先，我某處發現一個建議增加這.bashrc中：PKG_CONFIG_PATH = 「在/ usr/local/lib目錄/ pkgconfig」。幾個小時前我做了這個，它可能爲我解決了第一個問題。我不記得確實。

其次，我認爲ImageMagick的版本6.8已經過時需要這些方法：

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

等的早期版本仍然有他們。我在這裏遵循了一條指令（http://wearepandr.com/blog/article/homebrew-and-installing-old-package-versions）來安裝舊版本的軟件包。卸載imagemagick後，運行/ usr/local/Library/Formula /中的建議命令，然後重新安裝imagemagick，我能夠成功安裝rmagick gem。我隨機選擇了6.7.1-1種。

我真的認爲有人應該更新rmagick以反映更改它的依賴（這是陳舊的一年或兩年）。但我自己並不知情。

我建議切換到mini_magick寶石。您可以獲得ImageMagick提供的所有功能，但安裝更簡單，內存佔用空間稍低。
