尝试在Rails中设置simple_captcha时出现问题

Question

我目前正在开发一个Ruby(1.9) on Rails(2.3.4)应用程序。我想将验证码添加到其中，我遇到了Simple_Captcha插件，它安装得很好，但是当我尝试它的安装命令(rake simple_captcha)时，我给出了下面的错误

注意:我使用rake19是因为我安装了两个版本的Ruby1.9 (1.9和1.8.6 )，我通过添加19来运行Ruby1.9命令，例如gem19 ruby19 rake19..etc

有什么想法吗？

谢谢,

Answer 1

您提到过-我运行ruby1.9命令时添加了19，例如gem19 ruby19 rake19..etc

当您运行ruby -v时，终端上显示的版本号是多少

根据您在帖子中给出的错误，脚本正在尝试运行

ruby script/generate migration create_simple_captcha_data

根据您的评论，它应该看起来像

ruby19 script/generate migration create_simple_captcha_data
