APGL（另一个Python图形库）安装后测试错误

Question

有人成功安装了python的apgl图形库吗？http://packages.python.org/apgl/python中是否有其他替代的图形库以同样的简单性完成与apgl相同的工作？在

目前我正在使用Ubuntu12.04发行版，并在这里安装了相关库：

sudo apt-get install pip
sudo pip install numpy
sudo apt-get install libatlas-base-dev gfortran g++
sudo pip install scipy
sudo pip install matplotlib
sudo pip install agpl

它安装成功，然后当我安装时：

我遇到了一个错误：

在我看来，你好像遇到了某种Ubuntu的问题。在

   File "/usr/lib/python2.7/zipfile.py", line 464, in <module>
   class ZipExtFile(io.BufferedIOBase):
AttributeError: 'module' object has no attribute 'BufferedIOBase'

指示python安装有问题。在

是你自己安装的吗？在

另外。。。虽然pip很好，但是您应该更喜欢使用您的包管理器，并且只有当您必须安装真正的新版本或非打包版本时，才应该使用pip。因此，不是用pip do安装

然后用pip安装apgl。在

我在DebianWheezzy上成功地测试了我的安装apgl，并在今天（2012年9月13日）更新了包，测试结果很好。在
