諸事情あって、やっとYosemiteへのバージョンアップ許可がでたので アップグレードを繰り返してきたMacbook Airを、この機会にクリーンインストールに挑戦をしました。
愛用していた LockScreen2 が使えなくなったこと以外は購入済みのツールは復旧ができてひと安心 スクリーンロックは 電源 + s でディスプレイをオフにできるみたいなので、当面はこれで対応することにします。
順調に開発環境は整ったのですが、ターミナル向けツイッタークライアントの earthquake を動かすのに苦労したので書き残しておこうと思います。
環境は以下のとおり
- OS X 10.10.2
- Ruby 2.2.0
- earthquake 1.0.2
activesupportの読み込みに失敗する
インストール後、earthquakeを起動すると以下のエラーが出力されました。

この問題は ~/bin/earthquake:9 以下でactive_supportを読み込むことで解決しました。
require 'rubygems'
require 'active_support'
require 'active_support/deprecation'
パラメーターエラーの対応
次に、以下のようなパラメーター不足エラーが発生しましした。

この問題は ~/lib/ruby/gems/2.2.0/gems/twitter-stream-0.1.16/lib/twitter/json_stream.rb:206 を 以下のように変更することで解決します。
@buffer = BufferedTokenizer.new("\r", MAX_LINE_LENGTH)
↓
@buffer = BufferedTokenizer.new("\r")
不要な行をコメントアウト
次に、以下エラーが発生します。
/Users/kachina_t/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/twitter-stream-0.1.16/lib/twitter/json_stream.rb:27: warning: duplicated key at line 30 ignored: :path
この問題は ~/lib/ruby/gems/2.2.0/gems/twitter-stream-0.1.16/lib/twitter/json_stream.rb:27 を 以下のように変更することで解決します。

ここまでの修正で earthquake の起動は成功するのですが、25秒すると以下のエラーを出力して異常終了します。

if @state == :stream && !@buffer.empty?
↓
if @state == :stream && !@buffer.nil?
以上で、earthquakeが正常に動作するようになりました。
クリーンインストールしたので、すげー快適になりました。
あわせて、8系にアップグレードしてからモッサリしていたiPadもクリーンインストールしたら 驚くほど快適になりました。
週末を1日以上使ってしまったけど、大満足の結果です。
