ImageMagick 不允许我上传 jpg
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 .png 文件，它可以正常工作，如果我上传 .jpg 文件，它就不行。
这是当我尝试上传 jpg 时在我的视图中生成的错误：

以前有人遇到过这个吗？让我知道是否还有其他信息有帮助。
更新： 刚刚注意到 .jpg 文件在另一台计算机上可以正常上传（两台计算机分别运行 10.6/10.7）。这让我更加失落。我的另一台机器上可能配置错误？
I am running Paperclip 2.3.11 and ImageMagick 6.7.1-1.
I am uploading images to an Amazon S3 account.
If I upload a .png file it works fine, if I upload a .jpg it does not.
This is the error generated in my view when I try uploading a jpg:

Has anyone encountered this before? Let me know if any other info would be helpful.
UPDATE:
Just noticed that .jpg files do upload fine on a different computer (both are Macs running 10.6/10.7 respectively). This leaves me even more lost. What could be misconfigured on my other machine?

您应该安装 ImageMagick 的 JPG 支持。
这里是 jpegsrc 和 ImageMagick 的其他来源：
You should install JPG support for ImageMagick.

终于解决了这个问题。基于@floor的回答。 ImageMagick 在本机上不支持 jpg。我必须卸载并重新安装，然后也卸载并重新安装 Rmagick。现在一切正常。
Finally got this fixed. Based on @floor's answer. ImageMagick did not have jpg support on this machine. I had to uninstall and reinstall, then uninstall and reinstall Rmagick as well. Everything is working now.
