解決方法
必要なライブラリをインストール
Nokogiri 鋸 インストールチュートリアルがわかりやすい
brew install
上記チュートリアルとは異なるバージョンがインストールされるから注意
brew install libxml2 libxslt brew link libxml2 libxslt
libiconvはソースから
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz tar xvfz libiconv-1.13.1.tar.gz cd libiconv-1.13.1 ./configure --prefix=/usr/local/Cellar/libiconv/1.13.1 make sudo make install brew link libiconv
設定後bundle installでまだエラー orz
libiconv is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.
どうもライブラリの参照がおかしいっぽい
brew install する時にバージョンを指定
以下のコマンドを実行
bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib
実行後の ~/.bundle/config
--- BUNDLE_BUILD__NOKOGIRI: --use-system-libraries --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib
この設定でbundle installできた！！！！
