MailCatcher不能与VM上的rbenv一起使用

Question

我在使用rbenv管理的VM(VirtualBox)中安装了MailCatcher.但是,mailcatcher不起作用,在下面输出错误信息:

`require': cannot load such file -- i18n/core_ext/string/interpolate (LoadError)

似乎i18n没有安装,但我安装了它.

[vagrant@localhost ~]$ gem list i18n

*** LOCAL GEMS ***

i18n (0.7.0.beta1)

我在AWS EC2中安装与此相同,它可以工作.

我的VM发生了什么？

操作系统:CentOS 6.5

Ruby:2.1.1,rbenv 0.4.0

整个错误消息:

Answer 1

Rails 4.2 beta / activesupport-4.2.0.beta2 依赖于 i18n (< 0.8, >= 0.7.0.beta1)。

如果 mailcatcher (0.5.12) 加载 i18n 的 beta gem，则会抛出错误。

如果您不使用 Rails 4.2 beta 那么您可以卸载 beta 版本

gem uninstall i18n -v i18n-0.7.0.beta1

这在 gem 的多个问题中都被引用
