IOError：编码器 zip 不可用 ubuntu

Question

当我尝试运行使用 PIL 的 python 程序时出现以下错误。

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
    save_handler(self, fp, filename)

IOError: encoder zip not available

cpython 依赖于您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 之一。您应该可以使用 yum 或 apt-get 轻松安装这些。
