“ rmagick” gem安装问题

68

尝试在centos上安装“ rmagick” gem时出现问题。以下是我的输出。谁能帮我确定我缺少的包裹吗？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

错误消息显示：

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

看来您根本没有丢失任何软件包，您只需要告诉pkg-config在哪里可以找到MagickCore.pc文件来构建扩展即可。如果您已安装软件包，则ImageMagick-devel使用yum的文件应位于目录中/usr/lib/pkgconfig或/usr/lib64/pkgconfig（取决于您的体系结构）中。检查以下命令（从现在开始，我假设您在amd64机器上，如果不是，请替换lib64为lib）：

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

如果文件存在，则只需rmagick使用以下命令进行安装：

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

谢谢。您的建议有效。但是，我现在得到另一个输出（请检查已编辑问题的详细信息）。我不确定“由于某些原因，可能无法创建Makefile，可能缺少必要的库和/或头文件，请检查mkmf.log文件以获取更多详细信息。” 。另外，我是否需要安装输出中提到的开发版本？

嗨，是的，我只是确认确实安装了此glibc-headers lib。还有其他线索吗？
— 拉纳
在上面添加了mkmf.log文件的输出。请检查是否可以找到任何线索。我在Linux和Linux上都是新手，所以很多东西都输给我了:(。也有帮助

不，我没有从源代码编译任何软件包。我一直使用“ yum install”或“ gem install”安装打包的库。关于这个问题的答案：stackoverflow.com/questions/14355798/…，您认为对我来说也可能是类似情况吗？rmagick与imagemagick不兼容的版本？

在Ubuntu 16.04上，它现在是PATH =“ / usr / lib / x86_64-linux-gnu / ImageMagick-6.8.9 / bin-Q16：$ PATH” PKG_CONFIG_PATH = / usr / lib / x86_64-linux-gnu / pkgconfig gem install rmagick -v '2.13.2'

对于Mac与Brew，简单..

brew install imagemagick

这样便gem install imagemagick可以正常工作。

问题是，正如错误所言，

在pkg-config搜索路径中找不到软件包MagickCore

那里也建议解决方案：

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

所以，

  1. 查找MagickCore.pc的位置：

    sudo find / -name MagickCore.pc

  2. 如果未找到，则可能是您的系统上未安装ImageMagick-然后安装它（Google如何操作，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

这directory containing意味着您必须删除文件名才能起作用。这样PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig。

绝对！谢谢，@ sekrett

在Debian（不稳定），以解决此错误需要正确的包名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
