エラーの回避のやりかた

コマンドプロンプトで作成したファイル名にチェンジディレクトリします

例：cd c:￥ファイル名

gemfileの編集

コマンドプロンプトでvim gemfileと入力

gem 'nokogiri', '~> 1.6', '>= 1.6.7.rc3'

を書き足す

gemをインストール

gem install nokogiri -v 1.6.7.rc3 --pre

bundleアップデート

bundle update nokogiri

サーバーを建ててみる

rails server

結果

建てた

原因

nokogiriがエラーの原因だったかも・・・・
