我和其他应用程序有类似的问题但是又解决了创建应用程序的问题。但现在我有一些代码，所以我不想再创建它。
谁知道这里有什么问题？我有linux薄荷17 红宝石 2.1.4p265（2014-10-27修订版48166）[i686-linux] 轨道 4.1.8
答案 0 :(得分：10)
首先将其添加到您的Gemfile：
gem 'rb-readline'
其次是：
bundle install
如果这不能解决问题，请按照：
安装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
最后
bundle install
