在Django中获取无效的图像错误，但PIL已安装并通过所有测试 [英] Getting invalid image error in Django, but PIL is installed and passes all tests

问题描述

所以我终于通过Django（开发版本）和Python 2.6安装在/opt/python2.6上，在RHEL5上成功安装了PIL（经历了许多困难）。

So I've finally successfully installed PIL (after many difficulties) on RHEL5 with Django (development version) and Python 2.6 installed at /opt/python2.6.

运行selftest.py显示所有内容似乎都正确安装：

Running selftest.py shows that everything appears to be installed correctly:

$ python2.6 selftest.py 
57 tests passed.

我可以毫不费力地上传.png文件和.gif文件，但在尝试上传时遇到问题.jpg文件使用ImageField：上传有效的图像。您上传的文件不是图像或损坏的图像。

I can upload .png files and .gif files without difficulties, but run into problems when trying to upload .jpg files using the ImageField: "Upload a valid image. The file you uploaded was either not an image or a corrupted image."

我看到这个其他问题，并运行测试，看PIL是否会验证图像，它做了：

I saw this other question and ran the test to see if PIL would verify the image, and it did:

>>> from PIL import Image
>>> trial_image=Image.open("/tmp/jordanthecoder.jpg")
>>> trial_image.verify()
>>> 

可能发生什么事？显然，允许JPEG是很重要的。我意识到一个选择是使用FileField，然后检查以确保它是GIF，PNG或JPEG之一，但我宁愿使用内置对象。

What could be going on? Obviously, allowing JPEG is kind of important. I realize one option is to use a FileField instead and then check to make sure it is one of GIF, PNG, or JPEG, but I'd much rather use the built-in object.

如果这是有帮助的，这里是上面的shell的详细显示：

In case this is helpful, here is the verbose display for the shell above:

更新＃2：

好的，所以我决定完全绕过ImageField，看看PIL是怎么做的。这是有问题的代码（在我的views.py文件中）：

Okay, so I decided to bypass ImageField altogether and just see what PIL does on its own. This is the code in question (in my views.py file):

def test_image(request):
    i = Image.open("/tmp/jordanthecoder.jpg")
    t = i.verify()
    return HttpResponse("Image is "+repr(i.info))

这是网页输出：

Image is {'jfif_version': (1, 1), 'jfif': 257, 'jfif_unit': 1, 'jfif_density': (72, 72), 'dpi': (72, 72)}

更新＃3

所以，这些是模块和两个不同系统的路径。我不知道为什么他们是如此不同，我可以做什么来改变网页的行为。

So, these are the modules and paths for the two different systems. I'm not exactly sure why they're so different and what I can do to change the behavior of the web version.

他们实际上正在使用不同的JSON模块，漂亮这确实没有什么不同。除此之外，这里是不同的模块。假设这些模块都位于/opt/python2.6 /...

They actually were using different JSON modules, pretty sure that that makes no difference. Other than that, here are the different modules. Assume these modules are all somewhere in /opt/python2.6/...

只有在网络版本中：

django.contrib.sessions.*, django.core.email, django.core.handlers.*, django.core.mail, django.core.mimetypes, django.core.os, django.core.random, django.core.smtplib, django.core.socket, django.core.time, django.middleware.*, email.*, encodings.ascii, hmac, mimetypes, mod_wsgi, smtplib, uu

只有在shell版本中：

Only in the shell version:

code, codeop, django.core.management.*, readline, rlcompleter, settings, user

谢谢

**更新＃4 **

** UPDATE #4 **

看起来问题是apache使用不正确的libjpeg.so，而python正在使用正确的。我创建了一个更多的广义版本的问题，特定于Django

Looks like the problem is that apache is using the incorrect libjpeg.so, whereas python is using the right one. I've created a more generalized version of the question that isn't specific to Django.

是否可以控制apache使用的库？
