但是当我这样做时:
$ locate Magick-config
/opt/local/bin/Magick-config
/opt/local/share/man/man1/Magick-config.1.gz
/opt/local/var/macports/software/ImageMagick/6.6.4-9_0+q16/opt/local/bin/Magick-config

/opt/local/var/macports/software/ImageMagick/6.6.5-0_0+q16/opt/local/share/man/man1/Magick-config.1.gz
有什么想法吗?
这并不能完全解决问题,但是建议在Mac上安装Imagemagick和Rmagick的推荐方法是通过homebrew。这是我可以让Imagemagick和Rmagick在Mac上很好玩的唯一方法。
命令:sudo apt-get install libmagickwand-dev
对于Ubuntu(11.10+),请尝试安装libmagick ++-dev软件包。
对于其他Linux发行版,请尝试安装libmagick-dev软件包。
就我而言,我将其安装在Ubuntu / Linaro 4.5.2-8ubuntu3上,出现相同的错误,尝试安装以下两个软件包套件,并且它可以工作,也许是其中一个:
sudo apt-get install graphicsmagick-libmagick-dev-compat
sudo apt-get install libmagickwand-dev
在Mac上,在之后
我不得不将旧的应用程序转移到Debian拉伸服务器上。使用的红宝石版本为2.0.x。已安装imagemagick,其中包括libmagickwand-dev。尝试安装rmagick 2.13.2失败。
