Question

在rails 5.0.0中，我试图运行一个应用程序，但是bundle install无法运行，它显示错误，如

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

 current directory: /home/XYZ/shruthir/.rvm/gems/ruby-2.3.1/gems/rmagick-2.16.0/ext/RMagick
 /home/XYZ/shruthir/.rvm/rubies/ruby-2.3.1/bin/ruby -r ./siteconf20171012-7699-f2np4k.rb extconf.rb
 checking for gcc... yes
 checking for Magick-config... no
 checking for pkg-config... yes
 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

 Could not create Makefile due to some reason, probably lack of necessary

 Gem files will remain installed in /home/XYZ/shruthir/.rvm/gems/ruby-2.3.1/gems/rmagick-2.16.0 for inspection.
 Results logged to /home/XYZ/shruthir/.rvm/gems/ruby-2.3.1/extensions/x86_64-linux/2.3.0/rmagick-2.16.0/gem_make.out

 An error occurred while installing rmagick (2.16.0), and Bundler cannot continue.
 Make sure that `gem install rmagick -v '2.16.0'` succeeds before bundling.

In Gemfile:
  rmagick

如果我运行gem install rmagick -v '2.16.0'，则会显示与

相同的错误

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick:
ERROR: Failed to build gem native extension.

在谷歌搜索此问题并尝试通过运行sudo apt-get install imagemagick libmagickwand-dev进行修复，但同样显示错误，如

请帮助我解决此rmagick问题。

Answer 1

最新方法

PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16:$PATH"

gem install rmagick

方法1
rmagick gem在安装时无法找到PKG_CONFIG_PATH。我们需要告诉ImageMagick的路径存在于何处。添加bash总是更好。

export PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.9.3-7/lib/pkgconfig

方法2
如果上述解决方案无效，请尝试此操作你只需告诉pkg-config在哪里找到MagickCore.pc文件来构建扩展。如果您使用yum安装了包ImageMagick-devel，则该文件应位于/ usr / lib / pkgconfig或/ usr / lib64 / pkgconfig目录中（取决于您的体系结构）

试试这个

locate /usr/lib64/pkgconfig -name MagickCore.pc

或

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

如果文件在那里，您只需使用以下命令安装rmagick：

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