Rubygems，gemspec，可能的rvm錯誤

Question

升級到Rails 3.2和Rubygems時，出現錯誤消息。正如在stackoverflow建議，我跑了gem update --system升級Rubygems到1.8.24。在此更新之後，我運行了一條簡單的rails s命令，並且我運行的每個命令都會出現此持續性錯誤。

我RVM的版本是：1.17.7

我的Ruby版本是：ruby 1.9.2p320 (2012-04-20 revision 35421) [x86_64-darwin11.3.0]

當我運行bundle install，我得到一個錯誤：

"Could not find twitter-1.6.0 in any of the sources" 

當我運行rails -v，我得到一個錯誤：

could not find rack-1.2.3. run bundle install. 

我想我很在某些時候也可以用sudo命令安裝寶石，這可能會讓我的流程搞砸。有沒有辦法檢查？或糾正？

如果您認爲您安裝使用sudo你的Rails，試試：

ls -al ~ | grep .rvm 

~是$HOME快捷，所以該命令將列出你的home目錄，管道輸出到grep將搜索對於包含.rvm的列表。

您的.rvm文件夾應該歸您所有，看起來像列表中的rdo staff。我們希望將您的用戶ID和組值（默認爲staff）同時告知系統，讓您成爲.rvm目錄中所有文件的所有者。

sudo chown +r jdo:staff ~/.rvm 

這將遞歸下降到.rvm並重置文件和文件夾的所有權回到你們的一切RVM目錄裏面的內容，包括已安裝的紅寶石和他們的寶石。

請不要在驅動器上執行該命令，否則系統會變得非常不安，但是對於那個目錄，或者你認爲應該屬於你的用戶的那個命令，那就是......當您拉動扳機時，請小心指向正確的目錄。
