有人为python成功安装了apgl图形库吗？http://packages.python.org/apgl/ python 中是否有其他替代图形库可以与 apgl 执行相同的操作并具有相同的简单性？

目前我正在使用 Ubuntu 12.04 发行版，并且我已经在此处安装了依赖库：

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，然后当我这样做时：

>>> import apgl
>>> apgl.test()

我遇到错误：

>>> apgl.test()

在我看来，您遇到了某种 Ubuntu 问题。

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

表示您的 python 安装有问题。

你是自己安装的吗？

另外......虽然 pip 很棒，但您应该更喜欢使用包管理器，并且只有当您必须安装真正的新版本或非打包版本时，您才应该使用 pip。因此，不要使用 pip do 安装，

apt-get install python-scipy python-numpy python-matplotlib

然后才用 pip 安装 apgl。

我在 Debian Wheezy 上成功测试了我的安装 apgl，并在今天（2012 年 9 月 13 日）更新了软件包，测试结果很好。
