python - py2exe python 应用程序在 pyside 中使用 Chaco 时出错

Question

在此处输入代码我有一个程序，该程序使用嵌入在 pyside (Qt4) GUI 中的 Enthought Chaco 图。它还使用 numpy，但没关系。该程序直接从 Python 在多个平台上运行良好，但是当我使用 py2exe 创建 win32 的 .exe 时，运行 .exe 时出现错误:

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

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 相当陌生，但我感觉需要在我的 py2exe 安装文件中明确包含 Enthought 套件中的某些内容？有人有这方面的经验吗？

我没有使用过 py2exe，但我对 py2app 有一些经验(我认为这是相似的)。它无法包含许多 Enthought/chaco 包，因此您需要在 setup.py 中手动包含它们。这是我所做的:

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'],
      )

如果您替换使用类似的选项(当然将py2app替换为py2exe，并且可能将PyQt4替换为PySide >)，它可能对你有用。如果再次导入失败，只需将其添加到包含列表中即可。
