无法在Python中导入模块：PyQt4与SIP冲突

Question

我刚开始接触这个，英语也不太好，但我还是试试吧：我在我的电脑上装了最新的Arch Linux，昨天我尝试安装SIP，这是一个用于将C++代码封装成Python代码的工具。我在一个虚拟环境中尝试安装SIP和PyQt4。我从AUR（Arch用户仓库）获取了SIP，并按照这个方法安装的：

http://lucacerone.net/2013/08/installing-pyqt4-and-sip-in-a-virtual-environment-ubuntu-1204/#.Uyx-dGd_phF/

我这样做是因为在SIP的官方文档网站上，我没搞清楚该在哪里安装和放在哪个目录。文档对我来说不太清楚。现在我知道，这个想法很愚蠢，因为当我尝试用以下命令运行一个Python脚本时：

python file.py

我遇到了错误，因为我使用的是Python 3.3.4：

[vain@chinchi2 python_programme]$ python test.py
Traceback (most recent call last):
  File "test.py", line 25, in <module>
    import matplotlib.pyplot as plt
  File "/usr/lib/python3.3/site-packages/matplotlib/pyplot.py", line 98, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()
  File "/usr/lib/python3.3/site-packages/matplotlib/backends/__init__.py", line 28, in pylab_setup
    globals(),locals(),[backend_name],0)

  File "/usr/lib/python3.3/site-packages/matplotlib/backends/backend_qt4.py", line 21, in <module>
    import matplotlib.backends.qt4_editor.figureoptions as figureoptions
  File "/usr/lib/python3.3/site-packages/matplotlib/backends/qt4_editor/figureoptions.py", line 13, in <module>
    import matplotlib.backends.qt4_editor.formlayout as formlayout
  File "/usr/lib/python3.3/site-packages/matplotlib/backends/qt4_editor/formlayout.py", line 51, in <module>
    from matplotlib.backends.qt4_compat import QtGui,QtCore
  File "/usr/lib/python3.3/site-packages/matplotlib/backends/qt4_compat.py", line 56, in <module>
    from PyQt4 import QtCore, QtGui
RuntimeError: the sip module implements API v11.0 but the PyQt4.QtCore module requires API v10.1

我到底应该改什么呢？我还尝试过：

sudo pacman -S pyqt5-common 5.2-1 [installed]

（在python-pyqt5和python2-pyqt5之间共享的常用PyQt文件）和：

pacman -Sy python-qscintilla-common

也许存在错误的库依赖，我该如何解决这个问题？

哦，我想安装PyQt5，但在我执行了： python configure.py make sudo make install 后也遇到了同样的问题，错误依旧：

from PyQt4 import QtCore, QtGui RuntimeError: the sip module implements API v11.0 but the PyQt4.QtCore module requires API v10.1 [vain@chinchi2 python_programme]$ python2 erstenprog.py Traceback (most recent call last): File "erstenprog.py", line 26, in <module> import matplotlib.pyplot as plt ImportError: No module named matplotlib.pyplot

我感到非常沮丧，因为我在Arch Linux论坛用英语和德语发了帖子，但没有人回复我，只是让我卸载它。

我该怎么做呢？我是不是应该遵循这里的建议： http://lucacerone.net/2013/08/installing-pyqt4-and-sip-in-a-virtual-environment-ubuntu-1204/#.Uyx-dGd_phF/

我应该把PyQt5集成到：

full/virtualenv/path/build/PyQT5

因为它已经存在于：

lib/python3.3/site-packages/PyQt5。

error handling virtual environment pyqt5 library dependencies pyqt4 Arch Linux c++ integration sip
