PySide和PyQt在Windows 7下封装pylab时发生冲突。

I tried to package a small script which does some plotting with pylab. I used pyinstaller under Linux without a problem but under Windows 7 I get an error. On a different computer which has PySide but not PyQt installed the packaging worked. Thus by removing PyQt I can get it to work on my other computer. However, I would like to know if there is another way around this problem since I have some scripts which use PyQt and some which use PySide. I got a similar error by using cx_freeze.

我试着打包一个小脚本，用pylab做一些绘图。我在Linux下使用了pyinstaller，没有任何问题，但是在Windows 7下我得到了一个错误。在另一台装有PySide但没有PyQt的计算机上，包装工作。因此，通过删除PyQt，我可以让它在我的另一台计算机上工作。但是，我想知道是否有另外一种解决这个问题的方法，因为我有一些使用PyQt的脚本和一些使用PySide的脚本。我使用cx_freeze也犯了类似的错误。

Thanks for your help, Daniel

By following the suggestions from Pyinstaller --onefile warning pyconfig.h when importing scipy or scipy.signal I got rid of the warning but the error remains.

通过遵循Pyinstaller—一个文件警告pyconfig的建议。当导入scipy或scipy时。我去掉了警告信号，但错误仍然存在。

I had a closer look at the pyinstaller documentation and found a solution for pyinstaller. I used the excludes option in the Analysis block of the spec file:

我仔细查看了pyinstaller文档，找到了pyinstaller的解决方案。我在spec文件的分析块中使用了排除选项:

# -*- mode: python -*-
a = Analysis(['test.py'],
         pathex=['C:\\Workspace\\ZLC_python'],
         hiddenimports=[],
         hookspath=None,
         excludes=['PyQt4'],
         runtime_hooks=None)
for d in a.datas:
    if 'pyconfig' in d[0]: 
        a.datas.remove(d)
        break
pyz = PYZ(a.pure)
exe = EXE(pyz,
      a.scripts,
      a.binaries,
      a.zipfiles,
      a.datas,
      name='test.exe',
      debug=False,
      strip=None,
      upx=True,
      console=True )
