Rails rmagick错误Ubuntu c9.io

Question

我一直在寻找其他的rmagick线程来寻找一个好的解决方案。到目前为止，一切都没有奏效。

我正在做一个c9集成开发环境中的rails项目。我成功地通过'sudo apt get install imagemagick‘命令安装了imagemagick。

但是，当我尝试运行'gem install rmagick‘时，我得到以下错误

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

current directory: /usr/local/rvm/gems/ruby-2.3.0/gems/rmagick-2.15.4/ext/RMagick

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No package 'MagickCore' found checking for outdated ImageMagick version (<= 6.4.9)... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.  Check the mkmf.log file for more details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/usr/local/rvm/rubies/ruby-2.3.0/bin/$(RUBY_BASE_NAME)

To see why this extension failed to compile, please check the mkmf.log which can be found here:

 /usr/local/rvm/gems/ruby-2.3.0/extensions/x86_64-linux/2.3.0/rmagick-2.15.4/mkmf.log extconf failed, exit code 1

Gem files will remain installed in /usr/local/rvm/gems/ruby 2.3.0/gems/rmagick-2.15.4 for inspection.
Results logged to /usr/local/rvm/gems/ruby-2.3.0/extensions/x86_64-linux/2.3.0/rmagick-2.15.4/gem_make.out

Answer 1

试试这个(适用于rmagick 3.0.0)：

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