python - PIL python 的问题

Question

您好，我正在尝试使用 PIL 来通过管理界面将图像上传到我的 Django 网站。

这是我在安装 PIL 后运行的测试结果:

cfarm:Imaging-1.1.7 christopherfarm$ python selftest.py 
--------------------------------------------------------------------
PIL 1.1.7 TEST SUMMARY 
--------------------------------------------------------------------
Python modules loaded from ./PIL
Binary modules loaded from /Library/Python/2.6/site-packages/PIL
--------------------------------------------------------------------
*** PIL CORE support not installed
*** TKINTER support not installed
*** JPEG support not installed
--- ZLIB (PNG/ZIP) support ok
*** FREETYPE2 support not installed
*** LITTLECMS support not installed
--------------------------------------------------------------------
Running selftest:
*****************************************************************
Failure in example:
try:
 _info(Image.open(os.path.join(ROOT, "Images/lena.jpg")))
except IOError, v:
 print v
from line #24 of selftest.testimage
Expected: ('JPEG', 'RGB', (128, 128))
Got: decoder jpeg not available
1 items had failures:
   1 of  57 in selftest.testimage
***Test Failed*** 1 failures.
*** 1 tests of 57 failed.

在这方面我有点新手，有没有办法让所有类型都受支持？我也尝试上传一个 .png 文件，但还是不行。我收到错误消息:上传有效图像。您上传的文件不是图像或图像已损坏。

此外，在尝试运行 sudo python setup.py build 时，我收到以下错误:

指针好像有问题？

你必须安装对 JPEG 的支持，例如在 mac 中，如果你只使用自制软件:

brew install jpeg

或用于 ubuntu

sudo apt-get install libjpeg62-dev

您可能需要链接已安装的库，以便在 PIL 编译时知道到哪里寻找 JPEG 支持。这对于其他不受支持的库也是一样的。

还有一个叫pillow的选项，你可以看这里:http://pypi.python.org/pypi/Pillow

它只是在一些事情上比 PIL 更容易处理。还要检查 this
