我在安装rmagick时遇到问题。我正在使用Rails框架上的ruby开发我的项目。我在我的gemfile中包含了rmagick gem。我收到以下错误消息：
checking for ImageMagick version >= 6.4.9... no
Can't install RMagick 2.13.4. You must have ImageMagick 6.4.9 or later.
我已经使用brew安装了imagemagick：
imagemagick-6.8.9-8 already installed
imagemagick文件夹位于/ usr / local / Cellar目录中
在我的终端中：
Zoulfias-iMac：Myapp zoulfiahall $ rvm使用ruby-2.0.0-p481

任何建议将被认真考虑。
最佳答案
这对我在ubuntu上起作用。
$ sudo apt-get install imagemagick
$ sudo apt-get install libmagickwand-dev
现在再试一次。
$ bundle install
