Rails 控制台在我的生产服务器上不起作用。这是发生的事情：

root@myapp:/webapps/myapp/current# rails c
/usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- rails/cli (LoadError)
    from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /usr/local/rvm/gems/ruby-1.9.2-p180@rails/gems/rails-3.0.5/bin/rails:8:in `rescue in <main>'
    from /usr/local/rvm/gems/ruby-1.9.2-p180@rails/gems/rails-3.0.5/bin/rails:3:in `<main>'

以前我收到与 Readline 相关的错误，在这里解释：Rails 控制台、RVM 和 readline 的问题

我尝试了 propsoed 修复，现在我没有收到 readline 错误。控制台仍然无法启动。

这是 rvm 信息输出：

ruby-1.9.3-p194:

    RUBYOPT:      ""

在本地，我总是能够启动 rails 控制台，但在远程机器上有些不同。

upd：到目前为止，我最好的猜测是 Rails 缺少“rails/cli”的正确路径。必须进行研究，看看如何解决这个问题。

以普通用户身份安装 RVM 后，以普通用户身份重试。就我而言，以root
身份安装 RVM是一件痛苦的事，尤其是路径问题。

如果这不起作用，您可以随时切换到 rbenv。它更轻，并且在本地主机上拥有您需要的一切
