ruby-on-rails - Windows下的Rails 3 readline问题

Question

当我尝试运行 rails 控制台时，出现错误:

C:/ruby/Ruby193/lib/ruby/1.9.1/irb/completion.rb:9:in `require': cannot load suc
h file -- readline (LoadError)
        from C:/ruby/Ruby193/lib/ruby/1.9.1/irb/completion.rb:9:in `<top (requir
ed)>'
        from C:/ruby/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.9/lib/rails/c
ommands/console.rb:3:in `require'
        from C:/ruby/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.9/lib/rails/c
ommands/console.rb:3:in `<top (required)>'
        from C:/ruby/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.9/lib/rails/c
ommands.rb:38:in `require'
        from C:/ruby/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.9/lib/rails/c
ommands.rb:38:in `<top (required)>'
        from script/rails:6:in `require'
        from script/rails:6:in `<main>'

我已经安装了来自 http://gnuwin32.sourceforge.net/packages/readline.htm 的 readline但这对我没有帮助。

有什么建议吗？

readline是 ruby stdlib 的外部依赖项之一取决于。 RubyInstaller分发使用 pure-ruby implementation readline 代替 GNU-readline .

如果您最初没有使用 RubyInstaller 进行安装，我建议您使用它重新安装。它为您处理所有类似的外部依赖项。
