在openshift上部署时，未初始化的常量ActionView :: Helpers :: ActiveModelHelper
我试图在openshift上部署我的rails应用程序，但是我得到了这个错误。 Phusion Passenger显示此错误：您已经激活了机架1.5.2，但您的Gemfile需要机架1.6.0。 使用bundle exec可以解决这个问题。 （gem:: LoadError）

gem 'rack', '~> 1.6.0'
然后跑
bundle install
和
git push origin
这可能会迫使openshift环境使用最新的机架gem。
OpenShift内部依赖于RHEL 6.6 SCL ror40 ，其中包括机架版本1.5.2和乘客4.0.18。 不幸的是，这一切都不能像今天这样更新。
作为开始疑难解答步骤重命名Gemfile.lock（或删除它），然后重新安装捆绑bundle install
