我在尝试在 centos 上安装“rmagick”gem 时遇到问题。以下是我的输出。谁能帮我确定我缺少什么包裹？我已经安装了所有提到的另一个堆栈溢出线程：RMagick install error

这个ImageMagick 7 with RMagick 2.16 on MacOS Sierra Can't find MagickWand.h 适用于 Rmagick 2.16。

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

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

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ImageMagick-devel使用yum该文件安装了该软件包，则该文件应位于目录中/usr/lib/pkgconfig或/usr/lib64/pkgconfig（取决于您的体系结构）。使用此命令检查（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

如果文件在那里，您只需rmagick使用以下命令进行安装：

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

问题是，正如错误所说，

在 pkg-config 搜索路径中找不到包 MagickCore

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. 查找MagickCore.pc位置：

    sudo find / -name MagickCore.pc

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

  3. 像这样将它保存到 ENV var 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

对于带有 Brew 的 Mac，只需..

brew install imagemagick

然后gem install imagemagick就可以顺利工作了。

看起来您没有丢失任何包裹。错误信息很重要：

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

这个超级用户副本的几个答案给出了很好的建议。

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

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