An error occurred while installing rmagick (4.2.4), and Bundler cannot continue.
Make sure that `gem install rmagick -v '4.2.4' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  rmagick

I have installed pkg-config and imagemagick@6 with homebrew

I have followed various SO answers to debug, but nothing is working. How can I install rmagick ?

CodePudding user response：

As per the log:

ERROR: Can't install RMagick 4.2.4. Can't find ImageMagick with pkg-config

You don't have image magick installed. The following command should help.

brew install imagemagick

Install imagemagick and and then try bundle or install the gem manually gem install rmagick -v '4.2.4'
