CentOS6.9 i368の標準だとrubyは1.8.7だったりする。
新しいものを入れてみます。

RVM(Ruby Version Manager) を引っ張ってくる

RVM version 1.29.3 (latest) is installed yet 1.29.2 (latest) is loaded.
Please do one of the following:
* 'rvm reload'
* open a new shell
* 'echo rvm_auto_reload_flag=1 >> ~/.rvmrc' # for auto reload with msg.
* 'echo rvm_auto_reload_flag=2 >> ~/.rvmrc' # for silent auto reload.
# rvm reload Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-2.4.0/bin' is not at first place. Usually this is caused by shell initialization files. Search for 'PATH=...' entries. You can also re-add RVM to your profile by running: 'rvm get stable --auto-dotfiles'. To fix it temporarily in this shell session run: 'rvm use ruby-2.4.0'. To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.
