未定義的方法`每個'爲＃<字符串：0x00000003a27a58>

Question

首先，我真的很抱歉，因爲我還是這個新手。

我試着按照這個以下網站的說明安裝不含脂肪CRM：

http://www.blogdugeek.fr/crm-installation-fat-free-crm-debian-squeeze/

http://guides.fatfreecrm.com/Setup-Linux-or-Mac-OS.html

當我按照說明，我已經遇到了一些錯誤，並解決了一些。然而，在執行這個命令：

RAILS_ENV =生產耙分貝：創建分貝：遷移CRM：設置：負載

我被困在此命令行中，在這裏有以下的錯誤，我一直卡在：

rake aborted! 
NoMethodError: undefined method `each' for #<String:0x00000003a27a58>

因爲我搜索了更多相關的問題，我發現了一些，但它仍然沒有用。

另外，這裏有一些數據，可能需要：

這裏有誤差線

希望聽到並尋求一些建議和學習。 如果需要更多信息，請告訴我。

感謝，

Answer 1

你database.yml的問題。 YAML要求在密鑰和數據之間有一個分隔符。

所以不喜歡這樣的：

production: 
    adapter:mysql 
    encoding:utf8 
    ... 

但是這樣的：

production: 
    adapter: mysql 
    encoding: utf8 
    ... 

您需要更正文件中的所有行，因爲你有這樣的錯誤隨處可見。

Answer 2

再次檢查database.yml文件。不要添加任何東西 即文件格式必須正確。 已經不知情地發表評論，導致錯誤。
