自己チャレンジ用にRubyOnRails環境構築した時のメモ

Posted at

はじめに

自己チャレンジ・勉強用にRubyOnRailsでWebアプリを作りたい！リリースしたい！
と思いたち、環境構築したときの自分用メモです。
勉強用のページなので、間違いなどありましたらご指摘お願いしますm(_ _)m

作業環境

  • Windows 10 home 64bit
    • VMware(R) Workstation 14 Player利用
  • CentOS7 を仮想環境として利用.
$ cat /etc/redhat-release 
CentOS Linux release 7.5.1804 (Core) 

$ uname -a
Linux localhost.localdomain 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

rubyの更新

  • rubyのバージョン確認.
$ ruby -v
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]

  • rubyのバージョンアップをしようとこちらを参考にrbenvを導入する.

  • rbenv の最新であることを確認.

$ rbenv -v
rbenv 1.1.1-37-g1c772d5
  • インストールできるrubyバージョンからインストールバージョンを決定
    • 今回は、2.5.1をインストール.
$ rbenv install -l
Available versions:
  1.8.5-p52
  1.8.5-p113
  1.8.5-p114
  ...

ハマったポイント.

$ rbenv install 2.5.1
Downloading ruby-2.5.1.tar.bz2...
-> https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.bz2
Installing ruby-2.5.1...

となったので、ruby-build.20180729210820.13982.logを見てみる.

$ cat /tmp/ruby-build.20180729210820.13982.log

yum installが足りないと言われてるので（参考URLで最初にやれと書かれてますorz）、

$ sudo yum install -y openssl-devel readline-devel zlib-devel
...
インストール:
  openssl-devel.x86_64 1:1.0.2k-12.el7               readline-devel.x86_64 0:6.2-10.el7               zlib-devel.x86_64 0:1.2.7-17.el7              

依存性関連をインストールしました:
  keyutils-libs-devel.x86_64 0:1.5.8-3.el7             krb5-devel.x86_64 0:1.15.1-19.el7           libcom_err-devel.x86_64 0:1.42.9-12.el7_5        
  libselinux-devel.x86_64 0:2.5-12.el7                 libsepol-devel.x86_64 0:2.5-8.1.el7         libverto-devel.x86_64 0:0.2.5-4.el7              
  ncurses-devel.x86_64 0:5.9-14.20130511.el7_4         pcre-devel.x86_64 0:8.32-17.el7            

完了しました!

で必要なパッケージをインストールし、rubyのバージョンアップへ

$ rbenv install 2.5.1
Downloading ruby-2.5.1.tar.bz2...
-> https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.bz2
Installing ruby-2.5.1...
Installed ruby-2.5.1 to /home/administrator/.rbenv/versions/2.5.1

となった後、

$ export $PATH:$HOME/.rbenv/versions/2.5.1/bin/

でやっと、rubyの2.5.1が使えるようになる.
※$ rbenv rehash/$ rbenv global 2.5.1を実行してもダメでした...

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

gem の更新

  • gemのVersionを確認.
$ gem -v
2.7.6
  • gemをupdateする.
$ gem update --system
