The error message says:

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

It seems you missing no package at all, you just have to tell pkg-configwhere to find the MagickCore.pcfile to build the extension. If you have installed the package ImageMagick-develusing yumthe file should be inside the directory /usr/lib/pkgconfigor /usr/lib64/pkgconfig(depending on your architecture). Check with this command (from now I assume you are on a amd64 machine, if it's not the case replace lib64with lib):

似乎您根本没有丢失任何包，您只需要告诉pkg-config在哪里可以找到MagickCore.pc文件来构建扩展。如果您已经安装了ImageMagick-devel使用yum该文件的包，则该文件应该位于目录/usr/lib/pkgconfig或/usr/lib64/pkgconfig（取决于您的架构）。检查此命令（从现在开始，我假设您在 amd64 机器上，如果不是这种情况，请替换lib64为lib）：

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

If the file is there you just have to install rmagickwith this command:

如果文件在那里，您只需要rmagick使用以下命令进行安装：

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

For Mac with Brew, simply..

对于带有 Brew 的 Mac，只需..

brew install imagemagick

brew install imagemagick

Then gem install imagemagickwill work smoothly.

然后gem install imagemagick就可以顺利工作了。

The problem is, as the error puts it,

问题是，正如错误所说，

Package MagickCore was not found in the pkg-config search path

在 pkg-config 搜索路径中找不到包 MagickCore

The solution is also suggested there:

那里还建议了解决方案：

add the directory containing MagickCore.pcto the PKG_CONFIG_PATHenvironment variable

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

So,

所以，

  1. Find MagickCore.pclocation:

    sudo find / -name MagickCore.pc

  2. If it is not found, probably ImageMagick is not installed on your system —?then install it (Google how to do it, as it depends on the OS)

  3. Save it to the ENV var like that (make sure to put the path found in step 1):

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

  4. Retry installing RMagick

  1. 找到MagickCore.pc位置：

    sudo find / -name MagickCore.pc

  2. 如果没有找到，可能你的系统上没有安装 ImageMagick——然后安装它（谷歌怎么做，因为它取决于操作系统）

  3. 像这样将其保存到 ENV 变量中（确保放置在步骤 1 中找到的路径）：

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

  4. 重试安装 RMagick

It doesn't look like you're missing any packages. The error message is important:

看起来您没有丢失任何包裹。错误信息很重要：

Perhaps you should add the directory containing `MagickCore.pc' to the PKG_CONFIG_PATH environment variable

也许您应该将包含“MagickCore.pc”的目录添加到 PKG_CONFIG_PATH 环境变量中

Several of the answers on this superuser duplicategive good advice.

关于这个超级用户副本的几个答案给出了很好的建议。

On debian (unstable) the correct packages needed to resolve this error were libmagickcore-6.q16-dev, imagemagickand libmagickwand-6-headers

在 debian (unstable) 上，解决此错误所需的正确软件包是libmagickcore-6.q16-dev,imagemagick和libmagickwand-6-headers

I found them by using apt-file search MagickCore.pcand apt-file search MagickWand.h

我通过使用apt-file search MagickCore.pc和找到它们apt-file search MagickWand.h
