Python和py2exe - 隐含地导入模块 [英] Python and py2exe - Implicitely Importing Modules

问题描述

我过去曾多次使用py2exe为我的python程序创建* .exe文件。但是，这次我收到了一个错误。我想我知道问题是什么，但我不知道如何解决它。

I've used py2exe several times in the past to create *.exe files for my python programs. However, I'm getting an error this time. I think I know what the issue is, but I don't know how to resolve it.

我在子文件夹中有一些wx.Panels它可能是一个变量，所以我通过一个函数导入它们，找到文件夹中的* .py文件并调用下面的函数实际导入每个面板。

I have a handful of wx.Panels in a subfolder and it could be a variable amount, so I import them via a function that finds the *.py files in the folder and calls the function below to actually import each panel.

在普通的python中，这很好用。但是，py2exe会将这些文件保留。我认为因为它们没有明确导入，所以py2exe不相信它们是必需的。有针对这个的解决方法吗？我不知道py2exe中的一些选项？

In normal python, this works well. However, py2exe leaves these files out. I assume that because they are not explicitly imported, py2exe doesn't believe they are needed. Is there a solution to this? Some option in py2exe that I'm unaware of?

谢谢！

# module = Module to be imported (string)
# folder = Folder containing the module (string)
def import_module(module, folder=None):
   if folder is None:
      return __import__(module)
   return getattr(__import__('%s.%s' % (folder.replace(os.path.sep, '.'),
      module)), module)


...within some other function...
modules = [import_module(os.path.basename(os.path.splitext(filename)[0]), 'Panels') for filename in glob.glob('Panels//*.py')]

编辑

我正在添加一个我用过的示例setup.py脚本。但我已经使用了大约20种不同的变体和几种完全不同的脚本（我可以在互联网上找到）。请注意，一个要求是它在一个可执行文件中是完全自包含的。

I'm adding a sample setup.py script I've used. But I've used probably 20 different variations and several completely different scripts (what I could find on the internet). Note that one requirement is that it is completely self-contained in one executable file.

from distutils.core import setup
import py2exe

import wxversion
wxversion.select("2.8.12.1")
import wx
import wx.lib.pubsub

includes = []
excludes = ['_gtkagg', '_tkagg', 'bsddb', 'curses', 'email', 'pywin.debugger',
            'pywin.debugger.dbgcon', 'pywin.dialogs', 'tcl',
            'Tkconstants', 'Tkinter']
packages = ['wx.lib.pubsub']
dll_excludes = ['libgdk-win32-2.0-0.dll', 'libgobject-2.0-0.dll', 'tcl84.dll',
                'tk84.dll']

import glob
my_data_files = [('Panels', glob.glob('Panels/*.py'))]

setup(
    options = {"py2exe": {"compressed": 2,
                          "optimize": 2,
                          "includes": includes,
                          "excludes": excludes,
                          "packages": packages,
                          "dll_excludes": dll_excludes,
                          "bundle_files": 2,
                          "dist_dir": "dist",
                          "xref": False,
                          "skip_archive": False,
                          "ascii": False,
                          "custom_boot_script": '',
                         }
              },
    zipfile = None,
    #data_files = my_data_files,
    windows=['Main.py']
)

推荐答案

我相信我找到了解决问题的方法。在我的setup.py文件中，我将'includes = []'行替换为：

I believe I've found the solution for my issue. In my setup.py file, I replaced the 'includes = []' line with:

includes = ['Panels.%s' % os.path.basename(os.path.splitext(filename)[0]) for
        filename in glob.glob('Panels//*.py')]

在我使用'import_module'函数的代码中，它曾使用该glob来导入Panels目录中的模块。相反，我已经硬编码了要包含的模块列表。

In my code where I use the 'import_module' function, it used to use that glob to import the modules within the Panels directory. Instead, I've hard-coded a list of modules to include.

这不是我想要的确切解决方案（我不想硬编码面板列表），但似乎确实有效。除非我发现更好的东西，否则我将继续使用。

This isn't the exact solution I wanted (I don't want to hard-code that list of panels), but it does seem to work. Unless I discover anything better, this is what I'll continue to use.
