Creating plugins for standalone python executables

how to create a good plugin engine for standalone executable files created using pyInstaller, py2exe or similar tools?

I have no experience with py2exe, but pyInstaller uses import capture to import packages from it into a compressed repository. Of course, I can dynamically import another compressed repository created using pyInstaller and execute the code - it can be a simple plugin engine.

Problems arise when a plug-in (this is something that is imported dynamically) uses a library that is missing from the original repository (never imported). This is because the import hook is for the original application and is looking for packages in the original repository - not the one that was imported later (plugin package repository).

Is there an easy way to solve this problem? Maybe there is such an engine?

When compiling in exe you will have this problem.

The only option I can imagine to allow users to access their plugins to use any python library is to include all the libraries in the exe package.

py2exe.

py2exe , setup.py.

:

from distutils.core import setup
import py2exe

setup (name = "script2compile",
       console=['script2compile.pyw'],
       version = "1.4",
       author = "me",
       author_email="somemail@me.com",
       url="myurl.com",
       windows = [{
                    "script":"script2compile.pyw",
                    "icon_resources":[(1,"./ICONS/app.ico")]  # Icon file to use for display
                 }],
       # put packages/libraries to include in the "packages" list
       options = {"py2exe":{"packages": [   "pickle",
                                            "csv",
                                            "Tkconstants",
                                            "Tkinter",
                                            "tkFileDialog",
                                            "pyexpat",
                                            "xml.dom.minidom",
                                            "win32pdh",
                                            "win32pdhutil",
                                            "win32api",
                                            "win32con",
                                            "subprocess", 
                                        ]}} 

       )

import win32pdh
import win32pdhutil
import win32api
