ruby-on-rails – 安装rmagick时出错(2.16.0)[我尝试了Duplicate

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.

正如上面提到的那样,当我尝试使用gem install rmagick -v’2.16.0’时,它说

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick:

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.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib

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

extconf failed,exit code 1

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.

我已经尝试过在不同问题中提供的十几种不同的方法,但没有任何工作.
