Question

所以当我想安装zena时就开始了。但我搞砸了安装Ruby，gem，mysql的不同部分。到底。我最终正确地安装了zena，但是当我执行时：rake zena：init正如它在教程中所说的那样，我接受了：

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

/usr/local/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5... yes

Can't install RMagick 2.13.1. Can't find Magick-config in /usr/local/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:

Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.13.1 for inspection.
Results logged to /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.13.1/ext/RMagick/gem_make.out
Building native extensions.  This could take a while....

我希望我可以删除所有内容并重新安装ruby以及更正确的所有内容。谁能帮我这个？。感谢你们！

Answer 1

你在ubuntu上吗？

然后尝试安装此软件包：

sudo apt-get install libmagickwand-dev

如果这没有帮助，请尝试安装这些软件包：

sudo apt-get install build-essential ruby-dev

Answer 2

问题似乎与此类似 Can't install RMagick 2.13.1. Can't find MagickWand.h. 在那里试试我的答案。从发布的日志中，似乎找不到ImageMagick（这是必需的）。

Answer 3

当您收到依赖项错误时尝试此操作： E: Some index files failed to download. They have been ignored, or old ones used instead after apt-get update

否则请按照以下步骤操作：

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
