Question

我在尝试在centos上安装"rmagick"gem时遇到了问题.以下是我的输出.任何人都可以帮我确定我错过的包裹吗？我已经安装了所有提到的另一个堆栈溢出线程:RMagick安装错误

按照以下建议,现在我得到这个输出:

Answer 1

尝试安装

  sudo apt-get install libmagickwand-dev imagemagick

Answer 2

这在MacOS塞拉利昂ImageMagick的7 RMagick 2.16找不到MagickWand.h工程Rmagick 2.16.

brew install imagemagick@6
brew link --force imagemagick@6
gem install rmagick

Answer 3

错误消息说:

Package MagickCore was not found in the pkg-config search path.
Perhaps you should add the directory containing `MagickCore.pc'
to the PKG_CONFIG_PATH environment variable
No package 'MagickCore' found

看起来你根本没有丢包,你只需要告诉pkg-config在哪里找到MagickCore.pc构建扩展的文件.如果您已经ImageMagick-devel使用yum该文件安装了包,则应该在目录内/usr/lib/pkgconfig或/usr/lib64/pkgconfig(取决于您的体系结构).请使用此命令(从现在开始我以为你是AMD64的机器上,如果不是的情况下替换lib64用lib):

$ find /usr/lib64/pkgconfig -name MagickCore.pc

如果文件在那里,您只需rmagick使用此命令安装:

$ PKG_CONFIG_PATH='/usr/lib64/pkgconfig' gem install rmagick

Answer 4

对于带Brew的Mac,只需..

brew install imagemagick

然后gem install imagemagick会顺利进行.

Answer 5

问题是,正如错误所说,

在pkg-config搜索路径中找不到包MagickCore

在那里也提出了解决方案:

将包含的目录添加MagickCore.pc到PKG_CONFIG_PATH环境变量中

所以,

1. 找到MagickCore.pc的位置:

   sudo find / -name MagickCore.pc
   

2. 如果找不到,可能是你的系统上没有安装ImageMagick - 然后安装它(Google如何操作,因为它取决于操作系统)

3. 将它保存到ENV var(确保放置步骤1中找到的路径):

   PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig
   

4. 重试安装RMagick
