Ruby 1.9.3中的新樣式散列參數可用錯誤

Question

我剛將一個項目移動到另一個服務器，似乎自從Ruby 1.9.2以來可用的新的散列參數有問題。當我運行rails s我收到以下錯誤

from /var/www/myapp/config.ru:1 

錯誤是參考以下行

Myapp::Application.config.session_store :cookie_store, key: '_myapp_session' 

我真的不認爲上面的代碼行的問題。如果我刪除鍵：'_myapp_session'或將其恢復爲Ruby 1.8.X樣式，我只是得到下一個散列參數錯誤。

我移動的服務器最初在服務器上運行了Ruby 1.8.7。我更新了紅寶石1.9.3。當我運行ruby -v我得到ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

我不知道爲什麼我仍然有哈希問題。有沒有人遇到類似的問題？

Answer 1

您可能需要檢查路徑，看起來它使用的是1.8版本的Ruby可執行文件。當你升級時，你可能需要重新安裝寶石。這種情況是rvm是安裝ruby的首選方式的原因之一。

Answer 2

你應該發佈你懷疑有罪的代碼，很難回答這麼一點線索。

關於新風格的一個問題是，如果散列上的所有鍵都是符號，則只能使用它，這可能是問題。
