使用Chaco的py2exe Python应用程序出现错误

Question

我有一个程序，它使用了Enthought的Chaco绘图库，并嵌入在一个用pyside（Qt4）做的图形界面里。程序还用到了numpy，不过这没关系。这个程序在多个平台上直接用Python运行得很好，但当我用py2exe创建一个win32的.exe文件时，运行这个.exe文件时出现了错误：

Traceback (most recent call last):
  File "awesome_program.pyw", line 19, in <module>
  File "plotwidget.pyc", line 13, in <module>
  File "enable\api.pyc", line 8, in <module>
  File "enable\base.pyc", line 35, in <module>
  File "enable\colors.pyc", line 246, in <module>

  File "pyface\toolkit.pyc", line 38, in _init_toolkit
  File "pyface\toolkit.pyc", line 31, in import_toolkit
ImportError: No module named init

我的setup.py文件是：

#! /usr/bin/env python
# setup_win32.py

# Create an .exe for win32 systems.
# Run this with:
#   python setup_win32.py py2exe

import sys
from distutils.core import setup
import py2exe
# from cx_Freeze import setup, Executable

includes = []
includes.append("PySide.QtUiTools")
includes.append("PySide.QtXml")

base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(options = {"py2exe": {"dll_excludes":["MSVCP90.dll"],
                            "includes": includes}},
      name='awesomeprogram',
      version='0.01',
      description='A program to visualize stuff.',
      author='John Doe',
      author_email='dude@email.com',
      console=[{"script": "awesome_program.pyw"}])

我对Chaco和py2exe还比较陌生，但我觉得在我的py2exe设置文件中，可能需要明确地包含Enthought套件中的某些东西？有没有人有这方面的经验？

Answer 1

我没有用过py2exe，但我对py2app有一些经验（我觉得这两个挺像的）。py2app在打包时常常漏掉很多Enthought/chaco的包，所以你需要在setup.py文件里手动添加这些包。以下是我做的步骤：

OPTIONS = dict(
           includes = [
                       # The backends are dynamically imported and thus we need to
                       # tell py2app about them.
                       'kiva.*',
                       'enable.*',
                       'enable.qt4.*',
                       'pyface.*',
                       'pyface.ui.qt4.*',
                       'pyface.ui.qt4.action.*',
                       'pyface.ui.qt4.timer.*',
                       'pyface.ui.qt4.wizard.*',
                       'pyface.ui.qt4.workbench.*',
                       'traitsui.qt4.*',
                       'traitsui.qt4.extra.*',
                       'PyQt4.pyqtconfig',
                       'glob.*'],
           argv_emulation = True)

setup(
      app=APP,
      options={'py2app': OPTIONS},
      setup_requires=['py2app'],
      )

如果你用类似的OPTIONS（当然要把py2app换成py2exe，可能还要把PyQt4换成PySide），这样可能就能成功了。如果遇到其他的导入错误，只需把缺少的包加到包含列表里就行。
