我在通过rbenv管理的VM(VirtualBox)中安装了MailCatcher。
但是，mailcatcher不起作用，在下面显示错误消息:
`require': cannot load such file -- i18n/core_ext/string/interpolate (LoadError)
似乎没有安装i18n，但我已经安装了它。
[vagrant@localhost ~]$ gem list i18n
*** LOCAL GEMS ***
i18n (0.7.0.beta1)
我以同样的方式安装在AWS EC2中，它可以正常工作。
我的VM中会发生什么？

最佳答案
rails 4.2 beta/activesupport-4.2.0.beta2取决于i18n( = 0.7.0.beta1)。
如果mailcatcher(0.5.12)加载了i18n的beta版gem，则会引发错误。
如果您不使用Rails 4.2 Beta，则可以卸载Beta版本
gem uninstall i18n -v i18n-0.7.0.beta1
在gem的多个问题中都提到了这一点
