我试图得到样品heatmap.py运行： http://jjguy.com/heatmap/“IO错误：解码压缩不可用”：Ubuntu的Python的PIL
#image.py
import heatmap
import random
if __name__ == "__main__":
pts = []
for x in range(400):
pts.append((random.random(), random.random()))
print "Processing %d points..." % len(pts)
hm = heatmap.Heatmap()
img = hm.heatmap(pts)
img.save("classic.png")
，我得到这个错误：
Processing 400 points...
Traceback (most recent call last):
File "/home/ec2usr/workspace/image/image.py", line 14, in <module>
img.save("classic.png")
File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1437, in save
save_handler(self, fp, filename)
File "/usr/local/lib/python2.7/dist-packages/PIL/PngImagePlugin.py", line 572, in _save
ImageFile._save(im, _idat(fp, chunk), [("zip", (0,0)+im.size, 0, rawmode)])
File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFile.py", line 481, in _save
e = Image._getencoder(im.mode, e, a, im.encoderconfig)
File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 399, in _getencoder
raise IOError("encoder %s not available" % encoder_name)
IOError: encoder zip not available
在Ubuntu 12（64位）系统上使用Eclipse 2.7进行工作。
我在/ usr/lib和/ usr/lib/x86_64-linux-gnu中找到libz.so /很好。我已经尝试了这些解决方案，而结果：
PIL says it has "support available" but still gives IOError when saving files
About the PIL Error -- IOError: decoder zip not available
IOError: "decoder zip not available" using matplotlib PNG in ReportLab on Linux, works on Windows

我一直在拉我的头发在这几天，大大感谢任何人的帮助！

你有'libz.so'那里，当你安装PIL？ – wRAR 2013-03-06 21:25:54
我相信是这样，但是我之后也用sudo apt-get build-dep python-imaging重新编写了PIL蛋，以防万一。 – cmacdona101 2013-03-06 21:38:45
更新：.tif工作正常; PNG和JPG不起作用。 – cmacdona101 2013-03-06 21:48:37
