我已经在我的系统上安装了ImageMagick-6.9.0-Q16
。我正在使用rails-4和ruby-1.9.3
如果能帮我找到解决办法,我将不胜感激。提前感谢。最有可能的原因是可卡因4的API变化,而回形针还没有跟上。通过将以下行插入您的文件,尝试使用早期版本的可卡因:
gem“cookine”,“=0.3.2”Hello Dipak,没有its再次给出与添加gem“cookine”,“=0.3.2”后所解释的相同的错误消息在Gemfile中运行命令包更新。解决此错误的任何其他想法。请与我分享。看起来这已经被修复,因为回形针3.3:github.com/thoughtbot/paperclip/issues/1038截至2014年1月2日,回形针3.5.2需要可卡因~>0.5.3Dipak,我已经对您的评论做了一些小的更改。我做了gem“cookine”、“~>0.5.3”并且也进行了捆绑包更新..但是没有什么新的错误是相同的.无论如何,谢谢。。
