安裝rmagick時出現紅寶石錯誤

Question

所有這些都是在我想安裝zena時開始的。但我搞砸安裝Ruby，寶石，MySQL的不同部分。到底 。我用正確安裝澤納結束了，但是當我執行：耙澤納：初始化，因爲它在教程說，我receve：

ERROR: Error installing rmagick: 
    ERROR: Failed to build gem native extension. 

/usr/local/bin/ruby extconf.rb

我希望我可以刪除一切，更重新正確安裝Ruby和它的全部。誰能幫我這個 ？ 。感謝你們 ！

Answer 1

你在Ubuntu嗎？

然後嘗試安裝該軟件包：

sudo apt-get install libmagickwand-dev 

如果這沒有幫助，嘗試安裝這些軟件包：

sudo apt-get install build-essential ruby-dev 

Answer 2

這個問題似乎類似於 Can't install RMagick 2.13.1. Can't find MagickWand.h. 試試我的回答那裏。 從發佈的日誌中，它似乎根本找不到ImageMagick（這是必需的）。

Answer 3

試試這個，當你越來越依賴錯誤： E: Some index files failed to download. They have been ignored, or old ones used instead after apt-get update

否則遵循下述步驟：

sudo cp /etc/apt/sources.list ~/ 
sudo wget "http://pastebin.com/raw.php?i=uzhrtg5M" -O /etc/apt/sources.list 
sudo apt-get update 
sudo rm /etc/apt/sources.list.d/ubuntu-extras.list 
sudo apt-get update
