部署Rails应用程序：LoadError：无法加载此类文件 - I18n

Question

我想做什么

我正在尝试部署我的rails应用并运行bundle exec rake assets:precompile RAILS_ENV=production

错误消息

在我的开发者计算机上运行此命令可以正常工作。在我的服务器上运行它会出现此错误。我不知道机器上有什么不同。

我尝试了什么

• 包括i18n中的Gemfile gem 'i18n', '~> 1.0' - 没有帮助。
• 在调用rake任务之前用gem install i18n安装gem - 没有帮助。

非常感谢任何帮助。

低调'我'为我工作：

- require 'I18n'
+ require 'i18n'

虽然我不明白为什么它不起作用;在require 'I18n'中运行irb工作正常。
