Amazon Linux で bundle が cannot load such file -- io/console (LoadError) となる
bundle を実行しようとしたらエラーとなった
$ bundle -v /usr/share/ruby/vendor_ruby/2.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- io/console (LoadError) from /usr/share/ruby/vendor_ruby/2.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/vendor/thor/lib/thor/shell/basic.rb:2:in `<top (required)>' from /usr/share/ruby/vendor_ruby/2.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /usr/share/ruby/vendor_ruby/2.0/rubygems/core_ext/kernel_require.rb:55:in `require' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/vendor/thor/lib/thor/shell/color.rb:1:in `<top (required)>' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/vendor/thor/lib/thor/shell.rb:17:in `shell' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/ui/shell.rb:14:in `initialize' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/cli.rb:12:in `new' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/cli.rb:12:in `rescue in start' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/cli.rb:10:in `start' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/exe/bundle:19:in `block in <top (required)>' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/lib/bundler/friendly_errors.rb:7:in `with_friendly_errors' from /home/ec2-user/.gem/ruby/2.0/gems/bundler-1.11.2/exe/bundle:17:in `<top (required)>' from /home/ec2-user/bin/bundle:23:in `load' from /home/ec2-user/bin/bundle:23:in `<main>'
調べてみたところ、 ruby-devel か io/console のインストールが怪しそう。
ruby-devel から対応してみる。
$ sudo yum install -y ruby-devel 読み込んだプラグイン:priorities, update-motd, upgrade-helper amzn-main/latest | 2.1 kB 00:00 amzn-updates/latest | 2.3 kB 00:00 treasuredata/x86_64 | 2.5 kB 00:00 パッケージ 1:ruby-devel-2.0-0.3.amzn1.noarch はインストール済みか最新バージョンです 何もしません
最新だ。io-consoleを入れてみる。
$ gem install io-console Fetching: io-console-0.4.5.gem (100%) Building native extensions. This could take a while...

動いた。
$ bundle -v Bundler version 1.11.2
