“rmagick”的gem安装问题

我在尝试在centos上安装“rmagick”gem时遇到了问题。 以下是我的输出。 任何人都可以请帮助我确定我失踪的包 ？ 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

以下build议后，现在我得到这个输出：

gem_make.out的输出与上面的terminal输出相同。

Answer 1

尝试安装

  sudo apt-get install libmagickwand-dev imagemagick 

Answer 2

在MacOS Sierra上使用RMagick 2.16的ImageMagick 7无法find MagickWand.h适用于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 

看来你完全没有包，你只需告诉pkg-config在哪里findMagickCore.pc文件来构build扩展。 如果您已经使用yum安装了ImageMagick-devel软件包，则该文件应位于目录/usr/lib/pkgconfig或/usr/lib64/pkgconfig （取决于您的体系结构）。 检查这个命令（从现在我假设你是在一个amd64机器，如果不是这样的话，用libreplacelib64 ）：

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

如果该文件在那里，你只需要安装rmagick这个命令：

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

Answer 4

对于与Brew的Mac，简单地..

brew install imagemagick

然后gem install imagemagick将会顺利运行。

Answer 5

它看起来不像你想念任何软件包。 错误信息很重要：

也许你应该把包含`MagickCore.pc'的目录添加到PKG_CONFIG_PATH环境variables中

这个超级用户重复的几个答案给出了很好的build议。

Answer 6

在Debian（unstable）上，解决这个错误所需的正确软件包是libmagickcore-6.q16-dev ， imagemagick和libmagickwand-6-headers

我通过使用apt-file search MagickCore.pc和apt-file search MagickWand.h apt-file search MagickCore.pcfind他们

Answer 7

问题是，正如错误所述，

在pkg-configsearchpath中找不到包MagickCore

这里也提出了解决scheme：

将包含MagickCore.pc的目录添加到PKG_CONFIG_PATH环境variables

所以，

1. 查找MagickCore.pc位置：

    sudo find / -name MagickCore.pc 

2. 如果没有find，可能ImageMagick没有安装在你的系统上 – 然后安装它（谷歌如何做到这一点，因为它取决于操作系统）

3. 把它保存到ENV var（确保把步骤1中find的path）：

    PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig/MagickCore.pc 

4. 重试安装RMagick
