未初始化的常量ActiveSupport :: Dependencies :: Mutex（NameError） - 如何解决？ [英] Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError) - How to resolve?

问题描述

可能重复：
未初始化的常量ActiveSupport :: Dependencies :: Mutex（NameError）

嘿，我在整个网络上都看到过这个问题...任何人都可以解决这个问题吗？

我的应用程序是 RAILS_GEM_VERSION ='2.3。 5'除非定义？ RAILS_GEM_VERSION

我曾尝试在environment.rb，脚本/服务器和rake文件中使用线程，但这只是炸毁了日志...

我有使用1.8.7的rvm，我认为它是兼容的。但是我对rvm还是比较新的，所以我不确定它是否正常工作。

我有3个运行rails 2.x的应用程序，并且都遇到了这个问题。

Hey I have seen this issue a lot across the web... Anybody resolve this with any success?

My app is RAILS_GEM_VERSION = '2.3.5' unless defined? RAILS_GEM_VERSION

The log output

/Users/tjs/.rvm/gems/ruby-1.8.7-p352@rails2/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:55: uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

from script/server:4

I have tried requiring thread in the environment.rb, script/sever and rakefile but that just blows up the log...

I have rvm using 1.8.7 which I think is compatible. But I am still newer to rvm so not totally sure I have it working right.

I have 3 apps running rails 2.x and have this problem with all of them.

解决方案

http://ecmanaut.blogspot.com/2011/09/running-old-rails-238-with-rvm.html followed these steps and the app works again.
