Как и у многих других, у меня возникают проблемы при установке rmagick в Ubuntu при запуске комплектной установки.

Я получаю эту ошибку в команде установки пакета:

Installing rmagick (2.13.1) 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

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.

Gem files will remain installed in /home/selfsale/.bundler/tmp/2908/gems/rmagick-2.13.1 for inspection.
Results logged to /home/selfsale/.bundler/tmp/2908/gems/rmagick-2.13.1/ext/RMagick/gem_make.out

An error occurred while installing rmagick (2.13.1), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.

Затем я провел поиск и нашел несколько предложений по добавлению недостающих библиотек:

sudo apt-get установить libmagick9-dev:

Кажется, что любая попытка установить правильные пакеты приводит к этой проблеме.

Я только что видел сообщение об установке imagemagick из источника, поэтому я собираюсь попробовать это, но если у кого-то есть идеи получше, я бы хотел их услышать.

Спасибо
