Django ImageField“上传有效图像。您上传的文件不是图像或损坏的图像。“ [英] Django ImageField "Upload a valid image. The file you uploaded was either not an image or a corrupted image."

问题描述

我已经安装了PIL，但是当我尝试通过Django Admin为我的模型上传一个.png文件到一个图像字段时，我收到这个错误：

I have PIL installed, however whenever I try to upload a .png file to an image field through the Django Admin for my model, I get this error:

上传有效的图像，您上传的文件不是图像或损坏的图像。

"Upload a valid image. The file you uploaded was either not an image or a corrupted image."

其他图像类型工作正常。我已经尝试了几个不同的PNG文件。

Other image types work fine. I have tried several different PNG files.

我已经尝试在安装pypng，libpng-dev等之后重建PIL，并且在ubuntu服务器上。

I have tried rebuilding PIL after installing pypng, libpng-dev, etc.. and am on ubuntu server.

推荐答案

当您编译PIL时，应该说是否已经使用PNG支持编译，但是如果您在安装它时遇到问题你自己，我建议你使用ubuntu附带的版本。它是奇怪的命名，但很容易安装：

When you compile PIL it should say if it has been compiled with PNG support or not, but if you have problems installing it yourself, I would recommend that you use the version that comes with ubuntu. It's strangely named but easily installed with:

apt-get install python-imaging
