ruby-on-rails - 无法在ruby设置中分配RUBY_ENV变量

最近我开始在ruby on rails项目中工作。这是一个非常古老的项目。我是这项技术的初学者。请引导我。我的Gemfile包含

在完成bundle install之后。我正试着去做

RAILS_ENV=development bundle exec rake cache:generate

但是，我犯了错误，

我使用的是非常老的ruby版本。但是，我没有升级的选择。那么有办法解决这个问题吗？请引导我。这是我第一次看到1.9.3。谢谢您。

最佳答案

参阅Please require this file from within a Capistrano recipe (LoadError)
另外，您应该对gems进行分组，这样就不会部署（和加载！）根据生产环境开发和测试库。
例如，与Capistrano&Guard相关的所有内容都应位于group :development块中。
