PaperClip gem Paperclip :: Errors :: NotIdentifiedByImageMagickError

关于这个问题有很多Stackoverflow问题，但是经过几个小时后，我已经筋疲力尽了我能想到的每一个角度，当我尝试使用PaperClip gem（与PaperCrop一起上传）上传图像时仍然会出现以下错误：图片） .

我的环境：

• paperclip v4.3.6

• papercrop v0.3.0

• aws-sdk v1.66.0

• Rails 4.0.0

• Ruby 2.0.0p643

• Amazon S3用于文件存储

• OS-X Yosemite 10.10.5（Heroku Linux服务器上发生同样的错误）

我尝试过以下方法：

• 使用aws-sdk版本2或更高版本 .

• 卸载所有imagemagick安装（我最初有2个），然后用 brew install imagemagick 重新安装imagemagick

• 将PaperClip降级为4.1.1

• 包括：s3_credentials和：s3_permissions直接在模型中，如下所示：

has_attached_file：profile_image，：styles => {：thumb =>“50x50＃”，：medium =>“100x100＃”，：large =>“220x220＃”}，：storage =>：s3，：s3_credentials => {： bucket =>“XXX-development-bucket-us”，：access_key_id =>“XXX”，：secret_access_key =>“XXX”}，：s3_permissions =>“public-read”，：default_url =>'/ images /：attachment /missing：：style.jpg'validates_attachment：profile_image，content_type：{content_type：[“image / jpg”，“image / jpeg”，“image / png”]} crop_attached_file：profile_image，：aspect =>“1：1”

我认为它可能是一个s3权限问题，但我们的开发存储桶上的权限应该允许所有访问由密钥标识的用户 .

我还补充说......

Paperclip.options [：command_path] =“/ usr / local / bin”

...到环境/ development.rb .

我已经验证了ImageMagick正在使用命令行 .

还有什么想法可以看看吗？
