無法啟動Rails控制台

Question

Rails控制台在我的生產服務器上不起作用。 這是發生了什么：

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>'

以前我遇到了Readline相關的錯誤，在這里進行了解釋： rails控制台，RVM和readline的問題

我嘗試了固定修復程序，但現在沒有讀取行錯誤。 控制台仍無法啟動。

這是rvm info輸出：

ruby-1.9.3-p194:

在本地，我始終能夠啟動Rails控制台，但是在遠程計算機上則有所不同。

upd：到目前為止，我最好的猜測是Rails缺少指向“ rails / cli”的正確路徑。 必須進行研究，看看如何解決。

Answer 1

以普通用戶身份安裝RVM后，請以普通用戶重試。
據我所知，以root用戶身份安裝RVM是一件痛苦的事情，特別是我遇到了路徑問題。

Answer 2

如果那行不通，您可以隨時切換到rbenv。 它更輕巧，並且在本地主機上具有您所需的一切
