找不到Magick-config

Question

可能重复:
ImageMagick/RMagick - 无法安装RMagick 2.13.1.找不到Magick-config

当我尝试运行我的开发控制台(MAC OS X/Snow Leopard)时,我收到以下错误.有谁知道解决方案？

/usr/local/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5... yes
checking for gcc... yes
checking for Magick-config... no
Can't install RMagick 2.13.1. Can't find Magick-config in .:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

*** 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.

Answer 1

我通过安装解决了它 libmagickwand-dev

apt-get install libmagickwand-dev  
gem install rmagick

之前,我收到了以下错误(即使安装后libmagick9-dev):

apt-get install libmagick9-dev
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package libmagick9-dev is a virtual package provided by:
libmagickwand-dev 7:6.4.5.4.dfsg1-1ubuntu3.1
You should explicitly select one to install.
E: Package libmagick9-dev has no installation candidate

Answer 2

似乎这个问题在安装RMagick gem时很常见......我遇到了同样的问题,我在同一个站点找到了解决方案.点击此处的链接.

解:

sudo apt-get install libmagick9-dev

Answer 3

我遇到了类似的问题，因为我没有包含特定宝石的库。检查您的 gem，看看它们是否依赖于图像 gem 总是依赖的库。

config.gem gem_name, :lib => 'path_of_your_library'
