Disable autoinserted closed quote in ruby-mode emacs

I use ruby-mode for emacs, when I enter quote ", automatically inserted closed quote.

This is 开发者_开发问答maybe useful, but when I edit code it prevents, how I can disable this "feature"?

thanks.

Do you have

(require 'ruby-electric)

in your emacs config? If so, remove it.

Using ruby-mode alone doesn't cause the magic quotes you're seeing. Check also that you don't have autopair-mode enabled.
