rmagick
をインストールしようとしましたが、常にPKG_CONFIG_PATH
設定されていません。
これは私に複数回起こったので、私はこれを問題として投稿し、同じ問題に直面している他の人のために自分自身に答えています。

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.

rmagick
gemが見つかりませんPKG_CONFIG_PATH
インストール中。 ImageMagickのパスがどこにあるかを知る必要があります。 bashを追加するのは常に良い方法です。
export PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.9.3-7/lib/pkgconfig
同じ問題があります。私のためのこの作品(Ubuntu):
Sudo apt-get install libmagickwand-dev
CentOS
yum install ImageMagick-devel
これで問題が解決しました。
Sudo apt-get install libmagick++-dev
