如何為rails控制台安裝“readline”

Question

好吧，我正在嘗試運行“rails console”命令，但這是我得到的：

/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

如何安裝“readline”並使其正常工作？

Answer 1

我知道為時已晚。

沒有這樣的文件加載 - readline（LoadError）

嘗試將gem'rb gem 'rb-readline'到您的Gemfile中。）

Answer 2

rvm包已更改為rvm pkg

如果錯誤告訴我們這個會很好！ 啊!

Answer 3

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