我在 Ubuntu 16.04 上，
在 gemfile 我有 gem "rmagick" 并且当我 bundle 它说
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.
如上所述，当我尝试
gem install rmagick -v '2.16.0' 时，它说Building native extensions. This could take a while...
ERROR: Error installing 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

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.

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

Gem files will remain installed in /home/faisal/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/rmagick-2.16.0 for inspection.

我尝试了在不同问题中提供的十几种不同方法，但都没有奏效。
最佳答案
在 MacOS 中，您可以这样做:
brew unlink imagemagick
brew install imagemagick@6 && brew link imagemagick@6 --force
