久しぶりにRailsのbundle installではまった件
windows10のホスト上にvagrantでCentOSを載せている環境。
bundle installを実行したら以下のエラー。
$ bundle install --path=vendor/bundle
～略～

Results logged to /vagrant/privatepj/rails42/vendor/bundle/ruby/2.3.0/extensions/x86_64-linux/2.3.0-static/nokogiri-1.8.2/gem_make.out
An error occurred while installing nokogiri (1.8.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.8.2'` succeeds before bundling.
原因はプロジェクトの作成先ディレクトリが、vagrantでWindowsと共有しているフォルダだったための模様。 確かにエラーログを見るとビルドそのものに失敗している感じだった。
こういうエラー、久しぶりだ。Rails学習の初期にWindows上に環境作ろうとしてよくはまってた。 最近は仮想環境かMac上にしか作ってなかったから油断した。
