问题 I am currently using ambethia's recaptcha plugin for rails. I want to disable the message "incorrect-captcha-sol" whenever the user incorrectly enters the wrong recaptcha. How should I go about doing this?

问题 I found an example here showing how to install a Rails plugin. Their example shows this: ./script/plugin install calendar_helper This won't work for me because, confusingly, I don't have anything called plugin in my script directory. All I have is rails : $ ls script/ rails So Rails doesn't come with the script you need to install plugins? You need a plugin to install plugins? That doesn't seem very likely. Is something wrong with my Rails project? 回答1: You're probably on Rails 3. Replace .

However, you can install jRails then upgrade the jQuery installation simply replacing the javascript files (except jrails.js) in the javascripts
