通过Django上传JPEG图像显示错误 [英] Uploading a JPEG image via Django displays error

问题描述

我正在使用NGINX / FastCGI在Ubuntu的virtualenv中运行Django应用程序，并尝试将JPG图像上传到Django管理员应用程序。

我是得到此错误：上传有效的图像。您上传的文件不是图像或损坏的图像。我可以上传一个GIF图像，所以只有JPEG是造成问题的。

这是我迄今为止所尝试的：

1）在PIL之前安装libjpeg62-dev

  pip卸载pil 
 sudo apt-get libjpeg62- dev 
 pip安装pil 
  

在PIL安装结束时，我看到： p>

  PIL 1.1.7设置汇总
 ------------------ -------------------------------------------------- 
版本1.1.7 
平台linux2 2.6.5（r265：79063，2010年4月16日，13:09:56）
 [GCC 4.4.3] 
 ---- -------------------------------------------------- -------------- 
 *** TKINTER支持不可用
 --- JPEG支持可用
 --- ZLIB（PNG / ZIP）支持可用
 --- FREETYPE2支持可用
 *** LITTLECMS支持不可用
  

所以看起来像是JPEG支持。我也进行了手动测试以验证并验证：

 >>>来自PIL import Image 
>>> trial_image = Image.open（/ path / to / my / image.png）
>>> try_image.verify（）
  

2）与上述方法＃1相似，但手动指定JPG_ROOT： / p>

  pip卸载pil 
 sudo apt-get libjpeg62-dev 
 pip install --no-install pil 
 vi /path/to/virtualenv/build/PIL/setup.py（JPG_ROOT = libinclude（/ usr / lib））
 pip install pil 
  / pre> 
 
 
 3）尝试我的运气与枕头（一个PIL叉）
  pip卸载pil 
 sudo apt-get libjpeg62-dev 
点安装枕头
  
 
 
我正在运行Django，我也试着停止&在每次安装PIL后启动nginx服务。
 
 
 
到目前为止，上述方法都没有让我超越我在Ubuntu中的Django应用程序中的上述错误消息。我可以在我的本地开发框（Mac OSX 10.6.5）上上传相同的JPG图像，运行相同的Django应用程序，所以我知道这是我在Ubuntu上的部署。
 
 
 
任何帮助将不胜感激！
解决方案
你知道什么，我决定退出Django管理员重新登录....突然它工作正常！啧。我尝试的最后一件事是上面的＃2，所以如果有人遇到这个问题，那是你最好的解决方案。
 
I'm running a Django app inside a virtualenv on Ubuntu with NGINX/FastCGI and trying to upload a JPG image to the Django admin app.

I'm getting this error: "Upload a valid image. The file you uploaded was either not an image or a corrupted image." I can upload a GIF image, so it's only JPEG that's causing the problem.

Here's what I've tried so far:

1) Install libjpeg62-dev before PIL
pip uninstall pil
sudo apt-get libjpeg62-dev
pip install pil
At the end of the PIL install, I see:
PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version       1.1.7
platform      linux2 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)
              [GCC 4.4.3]
--------------------------------------------------------------------
*** TKINTER support not available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
--- FREETYPE2 support available
*** LITTLECMS support not available
So it looks like JPEG support is there. I've also done the manual test to verify and it verified:
>>> from PIL import Image
>>> trial_image=Image.open("/path/to/my/image.png")
>>> trial_image.verify()
2) Similar to approach #1 above, but manually specifying the JPG_ROOT:
pip uninstall pil
sudo apt-get libjpeg62-dev
pip install --no-install pil
vi /path/to/virtualenv/build/PIL/setup.py (JPG_ROOT = libinclude("/usr/lib"))
pip install pil
3) Try my luck with Pillow (a PIL fork)
pip uninstall pil
sudo apt-get libjpeg62-dev
pip install pillow    
I'm running Django under I've also trying stopping & starting the nginx service after each time installing PIL.

So far none of the above approaches have gotten me past the above error message in my Django app on Ubuntu. I can upload the same JPG image just fine on my local dev box (Mac OSX 10.6.5) running the same Django app, so I know it's something with my deployment on Ubuntu.

Any help would be appreciated!
解决方案
Well what do you know, I decided to log out of the Django admin and log back in....suddenly it works fine! Sheesh. The last thing I tried was approach #2 above so if anyone is having this problem, that's your best solution.
