退格键和箭头键在Windows机器上的IRB（Git Bash控制台）中不起作用

I just installed ruby 1.9.2 on windows machine and Backspace or any other arrow keys don't work. This happens only when I open IRB on Git Bash console. But it works fine on Windows console. Any help on that?

我刚刚在Windows机器上安装了ruby 1.9.2，Backspace或任何其他箭头键都不起作用。只有在Git Bash控制台上打开IRB时才会发生这种情况。但它在Windows控制台上运行良好。对此有何帮助？

Note: IRB was working fine on both consoles with the earlier versions of ruby.

注意：IRB在早期版本的ruby的两个控制台上运行良好。

Same thing happened to me. Running irb with --noreadline solved my problem:

同样的事情发生在我身上。使用--noreadline运行irb解决了我的问题：

irb --noreadline

You can also disable readline in ~/.irbrc

您还可以在〜/ .irbrc中禁用readline

IRB.conf[:USE_READLINE] = false

#3

Seems you didn't have readline installed while compile ruby. So install readline, maybe also readline-devel, then recompile ruby.

似乎你在编译ruby时没有安装readline。所以安装readline，也许readline-devel，然后重新编译ruby。

#4

Install the rb-readline gem.

安装rb-readline gem。

gem install rb-readline

As documented here https://groups.google.com/forum/#!topic/rubyinstaller/HgswOz1T-eE, use the below command/alias:

如此处所述https://groups.google.com/forum/#!topic/rubyinstaller/HgswOz1T-eE，请使用以下命令/别名：

alias irb="ruby -S irb"

If that doesn't work, use pry instead:

如果这不起作用，请使用pry代替：

gem install pry
