Python IOError:编码器zip不可用ubuntu

当我试图运行使用PIL的python程序时，我遇到了以下错误

Generate_Dot.py:14: RuntimeWarning: the frombuffer defaults may change in a future release; for portability, change the call to read:
  frombuffer(mode, size, data, 'raw', mode, 0, 1)
  img = Image.frombuffer('L', size, data)
Traceback (most recent call last):
  File "Generate_Dot.py", line 15, in <module>
    img.save('image.png')
  File "/home/kapil/python/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-i686.egg/PIL/Image.py", line 1439, in save

cpython依赖于系统中安装的各种第三方库。在这种情况下，需要“zip”来执行一些压缩。我猜在这种情况下，它将是gzip、compress或zlib中的一种。您应该能够使用yum或apt-get非常轻松地安装这些工具。

副本中答案的可能副本不适合他，因为他没有root访问权限。我已经阅读了上述链接并尝试过，但没有成功：-我没有根权限通过apt get下载和安装它。我从源代码在我的主目录中安装了zlib，但我一直在想如何将它链接到主目录中安装的python。使用libz.so将目录添加到您的LD_LIBRARY_PATH环境变量。导出LD\u LIBRARY\u PATH=~/mylibs/：$LD\u LIBRARY\u路径尝试添加到PYTHONPATH。
