Question

我正在开发一个关于Rails（2.3.4）应用程序的Ruby（1.9）。我想将Captcha添加到它中，然后我运行了Simple_Captcha插件，它安装得很好但是当我尝试使用setup命令时（rake simple_captcha）我给出了下面的错误

注意：我使用rake19，因为我有两个版本的Ruby（安装了1.9和1.8.6）我运行ruby 1.9命令，添加19例如gem19 ruby19 rake19..etc

任何想法？

Answer 1

你提到过 - 我通过添加19例命令来运行ruby 1.9命令。 gem19 ruby19 rake19..etc

运行ruby -v

时，终端上显示的版本号是多少？

根据您在帖子中提供的错误，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

HTH

尝试在Rails中设置simple_captcha时出现问题
