An error occurred while installing rmagick (2.13.2), and Bundler cannot
continue.
Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling.

Answer 1

您应该首先安装ImageMagick:

sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev

Answer 2

在Mac上,我做到了brew install imagemagick.

这成功地让我gem install rmagick -v '2.13.2'没有问题.
