"IOError:解码器zip不可用" :Ubuntu Python PIL [英] "IOError: decoder zip not available" : Ubuntu Python PIL
问题描述
我正在尝试从以下位置运行示例heatmap.py: http://jjguy.com/heatmap/
I am trying to get the sample heatmap.py running from: http://jjguy.com/heatmap/
#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
在带有Python 2.7的Ubuntu 12(64位)系统上使用Eclipse.
Working off of Eclipse on an Ubuntu 12 (64bit) system, with Python 2.7.
我在/usr/lib和/usr/lib/x86_64-linux-gnu/中都找到libz.so很好.我已经尝试了这些解决方案，但没有结果:
I find libz.so in both /usr/lib and /usr/lib/x86_64-linux-gnu/ just fine. I've tried these solutions already without result:
PIL表示具有可用的支持"但在保存文件时仍然会出现IOError
IOError:解码器邮编不可用"在Linux上的ReportLab中使用matplotlib PNG，可在Windows上使用

几天来我一直在梳头，非常感谢任何人的帮助！
I've been pulling my hair out over this for a few days and greatly appreciate anyone's help!

推荐答案
我刚刚遇到了类似的问题，这是因为同时通过apt-get安装了PIL(通过python pip安装程序安装)和python-imaging软件包引起的.当我从pip删除多余的版本时，为我解决了该问题.
I just encountered a similar issue caused by having both PIL (installed through the python pip installer) and the python-imaging package installed via apt-get. When I removed the extra version from pip that resolved it for me.
如果从源代码或使用pip安装了PIL，则可能会遇到相同的问题.
If you installed PIL from source or using pip then you might have the same problem.
在构建PIL时，我还发现必须将库链接到/usr/lib.这可能会解决您上面的日志中不支持的消息.
When I was building PIL I also discovered that I had to link over the libraries to /usr/lib. That might resolve the not supported messages in your log above.
sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib
sudo ln -s /usr/lib/x86_64-linux-gnu/libfreetype.so /usr/lib
sudo ln -s /usr/lib/x86_64-linux-gnu/libz.so /usr/lib
