Question

我在Mac上的Eclipse工作。我使用PyDev版本2.6.0.2012062818。我有一个运行完美的程序，但在我将Lion操作系统更新到Mountain Lion操作系统后，我在运行时遇到以下错误：

Traceback (most recent call last):
  File "/Users/Mihails/Projects/memsim/src/memsim/memsim.py", line 7, in <module>
     from simulation import SimulationHP
  File "/Users/Mihails/Projects/memsim/src/memsim/simulation.py", line 9, in <module>
     import matplotlib.pyplot as plt

   File "/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/matplotlib/backends/__init__.py", line 25, in pylab_setup

   File "/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/matplotlib/backends/backend_wxagg.py", line 23, in <module>
     import backend_wx    # already uses wxversion.ensureMinimal('2.8')
   File "/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/matplotlib/backends/backend_wx.py", line 63, in <module>
     backend_version = wx.VERSION_STRING
AttributeError: 'module' object has no attribute 'VERSION_STRING'

我根本不懂wx模块。我在site-packages中没有wx文件夹。我有wxPython。 wxPython init.py文件：

# The "old" wxPython package

import warnings

warnings.warn(
    "The wxPython compatibility package is no longer automatically generated "
    "or actively maintained.  Please switch to the wx package as soon as possible.",
    DeprecationWarning, stacklevel=2)

# We need to be able to import from the wx package, but there is also
# a wxPython.wx module and that would normally be chosen first by
# import statements.  So instead we'll have a wxPython._wx module and
# then stuff it into sys.modules with a wxPython.wx alias so old
# programs will still work.

import _wx
import sys
sys.modules['wxPython.wx'] = _wx
wx = _wx
del sys

from wx import __version__

Answer 1

我认为在您更新时，某些文件已被替换。

在Ubuntu 11.04 wx.VERSION_STRING上，返回字符串值。

尝试重新安装WX，或将'VERSION_STRING'附加到WX主文件。

Answer 2

我刚才遇到过类似的问题。我正在研究Winodws和MacOSX。

今天当我执行使用matplotlib和wx的python程序时，它只会弹出该消息。

我修复：我通过pip卸载了wx; 2.安装wxpython; 3.将matplotlib从1.2.0更新为1.2.1;

我想问题是我从pip安装的包wx根本不是wx而且它以某种方式覆盖了我的wxpython导入。

希望这些信息可以为您提供一些问题以及其他问题。

AttributeError：'module'对象没有属性'VERSION_STRING'
