Question

我正在进行铁路升级，并且能够成功将其转移到4.1.16

现在跳转到4.2 ...能够成功运行bundle update但是当我尝试运行我的规格时，我得到了一个不足SystemStackError遵循：

//home/vagrant/.rvm/gems/ruby-2.2.3/gems/arel-6.0.4/lib/arel/visitors/reduce.rb:14:in `rescue in visit': stack level too deep (SystemStackError)

我想知道这里需要更改/更新的内容，谢谢。

P.S：Ruby版本是2.2.3

#UPDATE： 我在之前的堆栈跟踪中犯了一个错误，错了，我现在已经更新了。

#Update（03/16）： 这似乎是由设计造成的...... 我设法将错误跟踪到config/initializers/devise.rb中的以下行：

require 'devise/orm/active_record'

Answer 1

我发现了......

所以，因为我试图避免this issue也有a stackoverflow post here，所以看起来我的设计版本太高了。

我之前正在运行设计3.2.1，我把它提升到3.5.1。如果我一次只更新一个宝石，我会注意到这一点......

但是，版本3.4.1现在对我很有用。

我可能还应该提到我的pg宝石版本是0.17.0。

Rails从arel升级到4.2堆栈太深的错误
