Ubuntu上的Ruby on Rails安裝錯誤

Question

我是一個新手入門。我剛開始學習Ubuntu，我正在使用版本10.04，特別是在rails上工作，並在我的大學項目中使用feedzirra。

我收到以下錯誤。能否請你幫忙。

anergroup@ubuntu:~/ruby$ ruby -v 
ruby 1.8.8dev (2010-10-01) [i686-linux] 
anergroup@ubuntu:~/ruby$ rails -v 
Rails 2.3.8 

我已經被

anergroup@ubuntu:~/ruby$ sudo gem list 

*** LOCAL GEMS *** 

actionmailer (2.3.8) 
actionpack (2.3.8) 
activerecord (2.3.8) 
activeresource (2.3.8)

rails (2.3.8) 
rake (0.8.7)

要啓動服務器，我輸入Ruby腳本/服務器

anergroup@ubuntu:~/ruby/testapp$ ruby script/server

爲什麼會出現這個錯誤寶石的名單？有沒有我失蹤的配置？

此外，是否有一個好的紅寶石的軌道emacs教程爲新手？

感謝您的幫助

Answer 1

看來你已經安裝了2個版本的Rails：2.3.8（在軌-v）和2.3.3（如在錯誤日誌）。強制應用程序中的較新的一個：

# config/environment.rb 
RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION 

可以用戶rvm在它們之間切換。然而，最簡單的事情是卸載Ubuntu-rails軟件包並安裝rails gem。

方法cookie_verifier_secret=已棄用，因此您可以安全地發表評論。
