python – 在Windows 7下打包pylab时PySide和PyQt发生冲突

我试图打包一个小脚本,用pylab做一些绘图.我在Linux下使用pyinstaller没有问题,但在Windows 7下我收到错误.在另一台安装了PySide而不安装PyQt的计算机上,包装工作正常.因此,通过删除PyQt我可以让它在我的其他计算机上工作.但是,我想知道是否有另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得到了类似的错误.

谢谢你的帮助,

显示问题的示例代码：

from pylab import *
labels = 'Cakes', 'Cookies', 'Biscuits', 'Tarts'
fracs = [27, 33, 14, 19]
pie(fracs, labels=labels, autopct='%1.1f%%', startangle=90)
show()

执行打包程序时产生错误：

ImportError: DLL load failed: The specified procedure could not be found.

通过遵循Pyinstaller –onefile warning pyconfig.h when importing scipy or scipy.signal的建议我摆脱了警告,但错误仍然存??在.

版本：

> Python 2.7.5
> PySide 1.2.1
> PyQt 4.9.6-3
> matplotlib 1.2.1
> numpy 1.7.1
> pyinstaller 2.1

解决方法:

我仔细看了一下pyinstaller文档,找到了pyinstaller的解决方案.我在spec文件的Analysis块中使用了excludes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 )
