尝试在Mac OS X上使用PIL作为图像绘制脚本。
安装了所有必需的库，运行＆＃39; python setup.py build_ext -i＆＃39;测试和JPEG显示为＆＃39;支持可用＆＃39;：
-------------------------------------------------------------------- PIL 1.1.7 SETUP SUMMARY -------------------------------------------------------------------- version 1.1.7 platform darwin 2.7.5 (default, Mar 9 2014, 22:15:05) [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] -------------------------------------------------------------------- --- TKINTER support available --- JPEG support available --- ZLIB (PNG/ZIP) support available --- FREETYPE2 support available --- LITTLECMS support available --------------------------------------------------------------------
然而，运行＆＃39; python selftest.py＆＃39;虽然显示为＆＃39;不支持＆＃39;：

重新安装libjpeg和pil没有任何效果。
