和我haved一样，与其他aplication问题，但解决了再创造的应用。但现在我有一些代码，所以我不想再次创建它。

有人知道这里有什么问题吗？

我有Linux Mint的17 红宝石 2.1.4p265（2014年10月27日修订48166）[i686的Linux的] 的Rails 4.1.8

Answer 1

开始加入这个您的Gemfile：

gem 'rb-readline' 

其次：

bundle install 

如果这不能解决问题，请按照此：

安装的readline：

sudo apt-get install libreadline-dev 

删除并重新安装Ruby

rvm remove 2.1.4  
rvm install 2.1.4 

终于

bundle install
