久々のRails開発なのだが

• 久々にRailsアプリを作る機会が発生したのだが、Mac内の環境がわからない。
• Rails4が進化してそうで、何だか面倒くさそー。
• サーバに環境作る時にエラーが出たら面倒くさそうー。
• NetBeansでデバッグできないから面倒くさそうー。

何だか、Javaの方がいい気がしてきた。
Javaの環境ではまることはそうそうない。Tomcat入れてデプロイするだけ。ライブラリも安定している。

言語は何でもいいんだけど、今回はRailsにする。

とりあえずrbenvの状況

kenmochi-no-MacBook-Pro:temp junya$ rbenv version
1.9.3-p392 (set by /Users/junya/.rbenv/version)
kenmochi-no-MacBook-Pro:temp junya$ rbenv versions
  system
* 1.9.3-p392 (set by /Users/junya/.rbenv/version)
  2.0.0-p247

1.9.3をメインで使っていたらしい。そういえば、簡単なWebアプリを作っていたな。。。
いつもそうだけど、RubyもRailsも最新を使う。

と思って、rbenv install -l を実行したが、Ruby 2.1が現れない。。。
ググってみたらrbenvが古いと出てこないとのこと。

以下を実行したが、うまくいかず。

brew update
brew upgrade ruby-build

結局ruby-buildを入れ直した。

brew remove --force ruby-build
brew install ruby-build

んで、インストール

kenmochi-no-MacBook-Pro:Cellar junya$ rbenv install 2.1.2
Downloading ruby-2.1.2.tar.gz...
-> http://dqw8nmjcqpjn7.cloudfront.net/f22a6447811a81f3c808d1c2a5ce3b5f5f0955c68c9a749182feb425589e6635
Installing ruby-2.1.2...

これが長い。。。

が、終了。

kenmochi-no-MacBook-Pro:Cellar junya$ rbenv rehash
kenmochi-no-MacBook-Pro:Cellar junya$ rbenv versions
  system
* 1.9.3-p392 (set by /Users/junya/.rbenv/version)
  2.0.0-p247
  2.1.2

global設定の変更

kenmochi-no-MacBook-Pro:~ junya$ rbenv global 2.1.2
kenmochi-no-MacBook-Pro:~ junya$ rbenv global
2.1.2

Rails4のインストール

ああ面倒くさい。

gem search rails
・・・
rails (4.1.4)
・・・
gem install rails

これも長そうだな。23:49開始。
終了。

rbenvを2.1.2に設定して、database.ymlを編集して、DB作成して、サーバ起動。

ようやく環境が整った！思っていたほど面倒ではなかった！

今回作るアプリはVPSを管理するもの。最初に作るのは１、２ページくらいのもの。VPSの状態を表示するのと、一斉にコマンドを実行する機能だけ。
それと、高速化するgemとか、いろいろ使ってみたいな、今回は。
