我正在尝试在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）

actionpack 4.2需要rack~＆gt; 1.6.0。您的Gemfile可能不包含rack gem。您可以尝试将此行添加到您的Gemfile
gem 'rack', '~> 1.6.0'
然后运行
bundle install
和
git push origin
这可能会迫使openshift环境使用最新的机架宝石。

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。

作为一个开始的疑难解答步骤重命名Gemfile.lock（或删除它），然后重新安装您的包bundle install
