rmagickのインストールでコケたのでメモ

More than 5 years have passed since last update.

Railsで画像アップローダ作ることがあって、サイズとかもいじりたいからrmagickをいれることにしたときちょっとコケたからメモ。


Gemfile

gem 'carrierwave' # アップローダにはcarrirwaveを使用

gem 'rmagick'

bundle

pkg-configないよと。。。

入ってるからリンクしなおしたら解決した。

brew unlink pkg-config

brew link pkg-config

これで解決。

gem install rmagick

bundle
