在 Windows 中，rails 控制台因“切换到检查模式"而失败 [英] rails console fails with `Switch to inspect mode` in windows

问题描述

我通过rails new foo创建了一个rails项目，然后cd foo，然后运行rails c.

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

然后我收到了这样的消息.

Then I got message like this.

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

仅此而已.我无法使用 rails 控制台.

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

你知道我做错了什么吗?

Have you any idea what am I doing wrong?

我正在使用 railsinstaller 和 ruby​​ 1.9.3 和 2.0.0，以及 ruby 2.0.0p451 (2014-02-24) [i386-mingw32]来自 Ruby 安装程序.所有版本都失败并出现相同的错误.

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.

简单的irb命令没有问题.

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

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

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

但信息保持不变.

推荐答案

万一有人在使用 Docker 时遇到这个错误，我得到它是因为我运行了 docker run rails 但需要 -it.

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

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