Python PIL安装-部分JPEG支持

正在尝试在Mac OS X上将PIL用于图像打印脚本

安装了所有必需的库，运行“python setup.py build_ext-i”进行测试，JPEG显示为“支持可用”：

但是，运行“python selftest.py”会显示为“unsupported”：

PIL 1.1.7 TEST SUMMARY

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.

重新安装libjpeg和pil并没有产生任何效果。

您使用pil而不是更新得多的东西有什么原因吗？我强烈推荐它……是的，我正在努力让它发挥作用：。我希望@jBender的可能副本也能与枕头一起使用。
