Ruby 是一種物件導向、命令式、函數式、動態的通用程式語言。這邊介紹如何在CentOS 7下安裝Ruby 2.5

(1) 安裝相關套件
# yum install gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel sqlite-devel

(2) Install RVM
# curl -sSL https://rvm.io/mpapis.asc | gpg --import -
# curl -L get.rvm.io | bash -s stable
# source /etc/profile.d/rvm.sh
# rvm reload

(3) Verify Dependencies
# rvm requirements run

Checking requirements for centos.
Requirements installation successful.

(4) Install Ruby 2.5
# rvm install 2.5

[Sample Output]

(5) 列出 Ruby 預設版本
# rvm list

(6) 確認 ruby 版本
# ruby -v

ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]

恭喜...這樣就安裝好囉
