This is an issue of Active Support and has been fixed with these two commits:
这是 Active Support 的问题，并已通过以下两个提交得到修复：
- https://github.com/rails/rails/commit/8fd52705eda6a2cd7e9a8a5bc723fa094e359eb7
- https://github.com/rails/rails/commit/3a30b12c774dfaa72acfe520e823374131631ea9
- https://github.com/rails/rails/commit/8fd52705eda6a2cd7e9a8a5bc723fa094e359eb7
- https://github.com/rails/rails/commit/3a30b12c774dfaa72acfe520e823374131631ea9
Unfortunately, these commits have been never included into the 3.2 releases, because the current last release (v3.2.21) was out on 18 Nov 2014 and after thatthese commits were merged.
不幸的是，这些提交从未包含在 3.2 版本中，因为当前的最后一个版本 (v3.2.21) 于 2014 年 11 月 18 日发布，之后这些提交被合并。
If you don't want to see this warning message definitely, you should change
your Gemfilelike this:
如果你不希望看到此警告消息肯定，你应该改变你的Gemfile是这样的：
# gem 'rails', '3.2.21' gem 'rails', git: 'https://github.com/rails/rails.git', branch: '3-2-stable'
Otherwise, you should downgrade ruby to 2.1 or wait the release of v3.2.22, which won't come until a grave security hole is found.
否则，您应该将 ruby 降级到 2.1 或等待 v3.2.22 的发布，直到发现严重的安全漏洞才会出现。
After all, there is no easy way to avoid this issue. Changing Gemfilefor such a trivial annoyance may be an overreaction in my view.
It will delay your deployment process quite a lot.
毕竟，没有简单的方法可以避免这个问题。Gemfile在我看来，为了这种微不足道的烦恼而改变可能是一种过度反应。它会大大延迟您的部署过程。

here is what i did to resolve that, i had the latest ruby and the gems are not compatible with that, so after having a fight for nearly a day i switched to older ruby version using rvm
这是我为解决这个问题所做的工作，我有最新的 ruby，但 gems 与它不兼容，所以在战斗了将近一天后，我使用 rvm 切换到旧的 ruby 版本
from ruby-2.2.1 to ruby-2.0.0 ,
从 ruby-2.2.1 到 ruby-2.0.0 ，
again this is not an issue with ruby version but incompatibility with gems,try and have good luck with that.
同样，这不是 ruby 版本的问题，而是与 gems 不兼容，请尝试并祝你好运。

好吧，这是一个解决方案：尝试在 .rbenv/.rvm 文件夹中进行所有这些更改并更改这些文件：

Hypothetically, updating to Rails 4.2.0 - which you should be able to do via the following commands - should fix this error, although it hasn't worked for me:
假设更新到 Rails 4.2.0（您应该可以通过以下命令进行）应该可以修复此错误，尽管它对我不起作用：
rvm use [email protected] --create
gem install rails
rails -v
I'm getting the same "circular argument error" message as well (I posted more about my failed attempts to fix it here, will update if I find an answer: Rails gem update not working (version 4.1.1 to 4.2.0) as a solution to "warning: circular argument reference" error).
我也收到了相同的“循环参数错误”消息（我在这里发布了更多关于我尝试修复它失败的信息，如果我找到答案就会更新：Rails gem update not working (version 4.1.1 to 4.2.0)作为“警告：循环参数引用”错误的解决方案）。

I altered the time_zone.rb file, instead of now=now, I entered now=Time.nowand problem solved.
我更改了 time_zone.rb 文件，而不是now=now，我输入now=Time.now并解决了问题。
