无法启动Rails控制台

Question

Rails控制台不能在我的生产服务器上工作。下面是发生的情况：

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>'

之前我收到了与Readline相关的错误，解释如下：Problems with the rails console, RVM and readline

我尝试了建议的修复，现在我没有得到readline错误。尽管如此，控制台还是无法启动。

以下是rvm信息输出：

在本地，我总是能够启动rails控制台，但在远程机器上则有所不同。

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

Answer 1

以普通用户身份安装RVM后，以普通用户身份重试。

根据我的经验，将RVM安装为root是一件痛苦的事情，我尤其遇到了路径问题。

Answer 2

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