Question

我遇到了这个问题几个小时。我无法在Windows中使用Railsinstaller环境运行rails c。

我尝试了ruby 1.9.3和ruby 2.0.0。

当我rails new console_test; cd console_test; rails c时，这是我得到的错误。

        from bin/rails:4:in `<main>'

我在gem 'rb-readline', '~> 0.5.1', require: false中添加了Gemfile，但它并没有解决问题。

我从here下载了readline5.dll，并重命名readline.dll并转到与ruby二进制文件相同的目录。但它也没有用。

我还能做些什么来解决这个问题？

修改的

我删除了C:\RailsInstaller\Ruby2.0.0和~/.gem，然后安装了新的Railsinstaller。

但仍有rb-readline错误。

我还下载并安装了Rubyinstaller和Devkit。即使rb-readline错误也没有消失。

Answer 1

我终于找到了，这个错误的原因。

我有~/.irbrc就是这样。

require 'irb/ext/save-history'
#History configuration
IRB.conf[:SAVE_HISTORY] = 100
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-save-history"

我只是删除了.irbrc，然后我可以毫无问题地使用rails console。

您是否尝试过运行此命令：

Tools | Run Rails Console...

无法使用Railsinstaller打开rails控制台
