Question

我有一个新的Rails安装，当我尝试运行控制台或任何rake任务时，我收到一条如下所示的错误消息：

$ rails c

        from script/rails:6:in `<main>'

任何可能导致此问题的想法？

感谢。

我认为这是readline

/。rvm / rubies / ruby-1.9.2-p320 / lib / ruby / 1.9.1 / irb / completion.rb：9：在`require'中：没有要加载的文件--readline（LoadError）< / p>

以下是一些资源：

https://rvm.io//packages/readline/

如果以上内容对您不起作用，那么您可以按照我的方式进行操作并使用此解决方案：

Rails3 and readline problem

在项目中包含rb-readline gem。（我不确定这是否被视为黑客攻击）

希望有所帮助。我花了一段时间才让控制台工作一次，而且有时令人沮丧。更不用说在更新一些Ubuntu软件包后我不得不再做一次。
