无法在Python上导入nodebox.graphics

Question

我试图在Python中使用NodeBox for OpenGL，但是我无法在Python2和3上导入库。

espaco@Arch ~> python2
Python 2.7.11 (default, Dec  6 2015, 15:43:46) 
[GCC 5.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from nodebox.graphics import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/nodebox_opengl-1.6-py2.7.egg/nodebox/graphics/__init__.py", line 1, in <module>
    import bezier
  File "/usr/lib/python2.7/site-packages/nodebox_opengl-1.6-py2.7.egg/nodebox/graphics/bezier.py", line 10, in <module>
    from context import BezierPath, PathElement, PathError, Point, MOVETO, LINETO, CURVETO, CLOSE
  File "/usr/lib/python2.7/site-packages/nodebox_opengl-1.6-py2.7.egg/nodebox/graphics/context.py", line 29, in <module>
    import geometry
  File "/usr/lib/python2.7/site-packages/nodebox_opengl-1.6-py2.7.egg/nodebox/graphics/geometry.py", line 454, in <module>
    from pyglet.gl import \
ImportError: cannot import name pointer
>>> 

espaco@Arch ~> python3
Python 3.5.1 (default, Dec  7 2015, 12:58:09) 
[GCC 5.2.0] on linux

>>> from nodebox.graphics import *
Traceback (most recent call last):

  File "/usr/lib/python3.5/site-packages/nodebox_opengl-1.6-py3.5.egg/nodebox/graphics/__init__.py", line 1, in <module>
ImportError: No module named 'bezier'
>>> 

我不知道Python2的错误，但是Python3One对我来说似乎是荒谬的，因为如果我在库目录bezier.py 上做了一个tree，我可以在那里看到：

espaco@Arch ~> tree /usr/lib/python3.5/site-packages/nodebox/

我为什么要犯这些错误？我怎样才能修好它们？

Answer 1

试试nodebox-opengl 1.6.1 + pyglet-1.3.3
