Rails3.2からRails4.0最新バージョンに上げたところsporkを起動できなくなりました。  
以下のようなエラーが出ます。

```

[こちら](http://qiita.com/yujinakayama/items/a1d31b2caa35642e8e69)を参考にrspecのバージョンも上げていこうと思いrspecのバージョンは2.99にしてます。  
他sporkのバージョンは以下の通りです。  
spork (1.0.0rc4)  
spork-rails (4.0.0)

読み込んでいるspec/spec_helper.rbコードは以下のようになっています。

```

     31   Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
     32
     33   RSpec.configure do |config|
     34     # ## Mock Framework
     35     #
     36     # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
     37     #
     38     # config.mock_with :mocha
     39     # config.mock_with :flexmock
     40     # config.mock_with :rr
     41
     42     # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
     43     config.fixture_path = "#{::Rails.root}/spec/fixtures"
     44
     45     # If you're not using ActiveRecord, or you'd prefer not to run each of your
     46     # examples within a transaction, remove the following line or assign false
     47     # instead of true.
     48     config.use_transactional_fixtures = true
    
```

spec/support/**/*.rbのとこにrequre
spec_helperが入ってたのでそれを除くとsporkは起動するようになりました。でもテストを流すと以下エラーになりました。

```

```

調べてみると、[書いてある通りgemを編集](http://qiita.com/etmnk/items/e1aa63b2f7f5615ac834)したら動作するようになりました。やっぱりgemを直接直すのも何なんでsporkではないものを使うべきでしょうか？

Rails 4.1からSpringがデフォルトでインストールされているようになっているので、SporkからSpringに切り替えるのをオススメします。  
僕も現在Sporkは使っていません。

Rails 4.0でもSpringは使用可能です。

Rails + Spring + Guard + RSpecを組み合わせる方法はネットにいろいろと載っていますし、僕が翻訳した「[Everyday
Rails - RSpecによるRailsテスト入門](https://leanpub.com/everydayrailsrspec-
jp)」でも解説しています。
