rails控制台在Windows中“切换到检查模式”失败

I create a rails project by rails new foo, then cd foo, and run rails c.

我通过rails new foo创建一个rails项目，然后是cd foo，并运行rails c。

Then I got message like this.

然后我得到了这样的消息。

DL is deprecated, please use Fiddle
Loading development environment (Rails 4.0.2)
Switch to inspect mode.

That's all. I can't use rails console.

就这样。我不能使用rails console。

Have you any idea what am I doing wrong?

你知道我做错了什么吗？

I'm using railsinstaller with ruby 1.9.3 and 2.0.0 both, and ruby 2.0.0p451 (2014-02-24) [i386-mingw32] from Rubyinstaller. All versions fails with same error.

我正在使用带有ruby 1.9.3和2.0.0的railsinstaller，以及来自Rubyinstaller的ruby 2.0.0p451（2014-02-24）[i386-mingw32]。所有版本都失败并出现相同的错

There is no problem with simple irb command.

简单的irb命令没有问题。

Edit

By following Graeme's advice, I updated rb-readline from 0.5.0 to 0.5.1. and uninstalled old one.

按照Graeme的建议，我将rb-readline从0.5.0更新为0.5.1。并卸载旧的。

$ gem list | grep rb-readline
rb-readline (0.5.1)

But the message remains same.

但信息仍然相同。

2 个解决方案

#1

In case anyone gets this error with Docker, I got it because I ran docker run rails but needed -it.

如果有人用Docker得到这个错误，我得到它，因为我运行了docker run rails但需要-it。

> docker run rails
Switch to inspect mode. # fail
> docker run -it rails
irb(main):001:0> # yay

#2

This is a known problem caused by the rb-readline gem in version 0.5.0. It has been subsequently fixed in 0.5.1 which came out a few months ago.

这是由版本0.5.0中的rb-readline gem引起的已知问题。它随后在几个月前发布的0.5.1中得到修复。

You should therefore upgrade the rb-readline gem to v0.5.1 to fix this problem.

因此，您应该将rb-readline gem升级到v0.5.1以解决此问题。
