Question

我正在运行Paperclip 2.3.11和ImageMagick 6.7.1-1。我正在将图像上传到Amazon S3帐户。

如果我上传了.png文件，那么它可以正常运行，如果我上传的是.jpg，则不会。

当我尝试上传jpg时，这是我视图中生成的错误：

3 errors prohibited this post from being saved:

我的日志是：

之前有没有遇到过这个？如果有任何其他信息有用，请告诉我。

更新：只是注意到.jpg文件做在另一台计算机上正常上传（两者都是分别运行10.6 / 10.7的Mac）。这让我更加失落。我的另一台机器上可能配置错误了什么？

Answer 1

您应该为ImageMagick安装JPG支持。

这是jpegsrc和ImageMagick的其他来源：

Answer 2

终于解决了这个问题。基于@ floor的答案。 ImageMagick在这台机器上没有jpg支持。我不得不卸载并重新安装，然后卸载并重新安装Rmagick。现在一切正常。

ImageMagick不让我上传jpgs
