将-gem“cookine”,“0.3.2”
添加到gemfile解决了这个问题
此处提供更多信息-作为调试步骤,您是否尝试从console创建映像,而不使用(嵌套)表单?e、 g.
Image.create:Image=>File.open('my_img.jpg')
如果是这样的话,那就行了吗?不,那不行!查看更新。然后至少我们知道表单不是问题;)嗯,我不太熟悉ruby on windows,但从您的错误来看,它似乎在临时目录中创建文件或从临时目录中读取文件时遇到了问题,在我看来,这不像是rmagick问题。恐怕我不能告诉你为什么。希望有更多windows经验的人能够发表评论。仅供参考,回形针不使用rmagick,只使用ImageMagick。您可以尝试一些更基本的方法来缩小问题的范围,例如直接通过曲别针执行identify
和convert
,例如paperclip.run(“identify file/name.jpg”)
。另外,当您试图弄清楚这一点时,请对AmazonS3进行注释。您是否在操作系统下安装了rmagic本机库?
