active_support/secure_random LoadError

Question

我正在將我的rails應用程序從Rails 2.3遷移到3.2。我有ActiveSupport 3.2依賴項，但在應用程序啓動時，我不停地收到以下錯誤。我沒有在我的代碼中的任何地方使用active_support/secure_random。有人可以幫我解決這個問題嗎？ 錯誤日誌 -

Answer 1

ActiveSupport::SecureRandom從軌3.2移除，因爲鋼軌3.2需要Ruby 1.8.7已經有一個內置的SecureRandom。

更換任何需要與

require 'securerandom' 

而且使用SecureRandom代替。

如果您不是直接使用SecureRandom，那麼您可能使用的是一個gem，例如舊版本的設計。
