未初始化的常量ActiveSupport :: Dependencies :: Mutex

Question

我嘗試從OSX運行一個正在運行的rails項目到Debian。我在兩個系統上使用RVM，併爲該項目創建了相同的gemsets和rvmrc。在Debian上我只安裝了ruby和rvm，沒有系統安裝ruby存在。

當我在項目文件夾中跳轉rvm正在切換到1.8.7版本並且正在使用項目gemset時，一切看起來都很好。

但是當我火了一耙-T我得到這個錯誤：

Answer 1

我的工作解決方案。添加以下行：

require 'thread' 

Railsfile在您的rails項目根目錄的第一行。神奇地所有將運行;-)

Answer 2

我碰到了這個自己不是很久以前。如果你谷歌它，你會發現一些博客和郵件列表帖子，建議你在你的environment.rb明確require "threads"。然而，這並沒有爲我工作，但降級的RubyGems做：

sudo gem update --system 1.3.7 

一些帖子還提到升級到Rails的一個新版本，這是不是在我們目前的情況選擇。

Answer 3

對我來說，添加要求'thread'也沒有工作。

它的rubygems新版本之間和軌舊版本（在我的情況2.3.5）

的兼容性問題（在我的情況，1.8.5）： 問題被降級 rubygems到1.4.2解決

$ gem install rubygems-update -v='1.4.2' 

$ gem uninstall rubygems-update -v='1.8.5' 

$ update_rubygems 

Answer 4

可以通過升級軌

gem install rails --version 2.3.11 

解決它或降級寶石

sudo gem update --system 1.5.3
