如何为rails控制台安装“readline”

好吧，我正在尝试运行“rails console”命令，但这是我得到的：

/home/user/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/irb/completion.rb:10:in `require': no such file to load -- readline (LoadError) from /home/user/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/irb/completion.rb:10 from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands/console.rb:3:in `require' from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands/console.rb:3 from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands.rb:37:in `require' from /home/user/.rvm/gems/ruby-1.8.7-p352/gems/railties-3.1.0/lib/rails/commands.rb:37 from script/rails:6:in `require' from script/rails:6 

如何安装“readline”并使其正常工作？

Answer 1

我知道为时已晚。

没有这样的文件加载 – readline（LoadError）

尝试将gem’rb gem 'rb-readline'到您的Gemfile中。）

Answer 2

rvm包已更改为rvm pkg

如果错误告诉我们这个会很好！ 啊!

Answer 3

 $ rvm uninstall 1.8.7 $ rvm package install readline $ rvm install 1.8.7 -C –with-readline-dir=$HOME/.rvm/usr
