I've been noticing this... probably since I first started using Python 3.10:

0$ python setup.py py2exe
C:\Users\Athan\Documents\Devel\infi-systray_py2exe\setup.py:1: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives
  from distutils.core import setup
running py2exe

Do you have any plans for migrating py2exe itself away from using distutils ?

I have a vague memory of you deprecating use of build_exe.exe, but even if that's correct then it's still installed along with py2exe and will output a setup.py that uses distutils:

[email protected] MINGW64 ~/Documents/Devel/infi-systray_py2exe (main)
0$ build_exe.exe -W setup-build_exe.py sample_systray.py
Created setup-build_exe.py.
[email protected] MINGW64 ~/Documents/Devel/infi-systray_py2exe (main)
0$ head setup-build_exe.py
#!/usr/bin/python3
# -*- coding: utf-8 -*-
# Created by: python.exe -m py2exe -W setup-build_exe.py sample_systray.py

from distutils.core import setup
...

Obivously there's currently plenty of time. Python 3.12 will likely be available around October 2023, so still 19 months to go yet. But it would still be better to address this sooner rather than later.

We've been trying to get Windows system tray icon support into our project using infi.systray. It works, but we're having trouble getting py2exe to package it properly.

Our issue is https://github.com/EDCD/EDMarketConnector/issues/1020

I've made an example code repo at https://github.com/Athanasius/infi-systray_py2exe

The main branch of that tries to do the bare minimum and gets the error as shown in https://github.com/Athanasius/infi-systray_py2exe/blob/main/sample_systray-bare-setup.log

The setup-pkg_resources branch then attempts to include pkg_resources but gets the error as shown in https://github.com/Athanasius/infi-systray_py2exe/blob/setup-pkg_resources/sample_systray-with-pkg_resources.log

Adding 'packages' to py2exe packages option gets us a little further... but then can't import other things. This is where I realised that pkg_resources includes a copy of packages in pkg_resources._vendor, but:

1. That isn't recognised by py2exe as a package (__path__ is missing?)
2. Doesn't work if included as a module instead.

I realise this whole thing is because pkg_resources and packages are doing their own module importing directly, which makes it tricky for py2exe to find the correct files to include in the build.

Picking up on discussion from #18, I was able to get a few packages to work by specifying the package names in the options, but one it did not work for is pyproj.

On Python 3.7.x (32 and 64-bit), same setup as in #18, but with pip install pyproj==2.2.2 to get a windows wheel. The following is the output of the resulting exe, with a bonus warning about distutils which I don't know is related. The last import, pyproj._crs is a pyc in the zip that loads a pyd outside the zip.

In python 3.7 and up, _ssl.pyd relies on libcrypto and libssl. These aren't picked up by py2exe, which is problematic for NVDA (see https://github.com/nvaccess/nvda/issues/9831)

This patch is based on https://github.com/anthony-tuininga/cx_Freeze/pull/470 by @sekrause. I made sure that after building an NVDA distribution with this patch applied, the libcrypto and libssl modules were copied successfully.

Originally reported as https://github.com/nvaccess/nvda/issues/12357 as this issue stops us from upgrading to post 0.10.1.0 versions of py2exe.

To reproduce try to freeze py2exesample.zip with version 0.10.1.0 and then with any later versions including the latest 0.10.4.1. While with 10.1.0 the freezing process works as it should all later versions provide the following error:

Obviously the reproducer attached above is extremely silly and it would be easy to rewrite it, but as mentioned above we follow similar pattern in NVDA and it would be pretty difficult to modify its code so that this bug is not triggered. As soon as the line from .functions import my_avesome_func in samplePKG\__init__.py is commented out the program can be frozen successfully.

hello, i am a new programmer. i want to write a tools then share it with others。 the python version is: Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 16:07:46) [MSC v.1900 32 bit (Intel)] on win32 py2exe version is: 0.9.3.2 when i write a program with pandas or matplotlib package，then package it using py2exe,i got a error like this: File "C:\Program Files (x86)\Python36-32\lib\site-packages\py2exe\mf3.py", line 215, in _resolve_name raise ValueError('attempted relative import beyond top-level package') ValueError: attempted relative import beyond top-level package.

my program is a test,no meaningfull functions in it,as follows: import matplotlib.pyplot as plt input('pause') my setup file's content is: from distutils.core import setup import py2exe setup(console=['demo_py2exe_python3.py']) If anyone could help me?thanks very much.

semantic_version 2.8.5 / semantic_version/__init__.py:

from .base import compare, match, validate, SimpleSpec, NpmSpec, Spec, SpecItem, Version


__author__ = "Raphaël Barrois <raphael.b[email protected]>"
__version__ = '2.8.5'

That works with py2exe, no problem.

semantic_version 2.9.0 / semantic_version/__init__.py:

# -*- coding: utf-8 -*-

# This code is distributed under the two-clause BSD License.


from .base import compare, match, validate, SimpleSpec, NpmSpec, Spec, SpecItem, Version

try:

    from importlib.metadata import version

    __version__ = version("semantic_version")
except ImportError:
    import pkg_resources

    __version__ = pkg_resources.get_distribution("semantic_version").version

This does not work with py2exe because py2exe only packages the necessary files from the semantic_version/ directory, and nothing from the accompanying semantic_version-2.9.0.dist-info/ directory (NB: 2.8.5 has an equivalent). This then leads to the error:

Numpy now works fine with the dll embedded in the exe which is great.

But with other dlls, like soundfile, the exe fails with either a silent crash or errors like the one in the title. Using a hook to insert it into the bundle does not, alone, solve the issue. In this case it tries to load it via cffi with a path as parameter.

We had a headscratcher today, trying to figure out why the GitHub build of our application resulted in a broken install, when it worked perfectly fine from source, and even when built locally.

We finally tracked this down to how py2exe does both of these:

Copy DLL C:\hostedtoolcache\windows\Python\3.7.9\x86\DLLs\libcrypto-1_1.dll to dist.win32\
Copy DLL C:\Program Files\Amazon\AWSCLIV2\libcrypto-1_1.dll to dist.win32\

When we checked a prior build it had also done this double-source copy, but in the other order, so we ended up with the correct version of the file. That 'Amazon' DLL is a 64-bit one so plain doesn't work with our 32-bit program.

So, two issues:

1. Why does py2exe copy a DLL twice, from a different source each time ? Surely it should either pick one and stick to it, or alert you that you need to make a decision. Especially important as in some sense the order might be random (we can't easily tell without further investigation if GitHub changed the order of a PATH).
2. If py2exe knows it's building a 32-bit executable then it should take steps to not copy any 64-bit DLLs, and I assume vice versa.

Edit: One of these days I'll remember that GitHub issues need the closing triple-backtick on its own line.

Just ran across a bug in py2exe where it doesn't add passlib automatically and even including passlib in the packages option doesn't help. See the following code:

from passlib.apps import custom_app_context
print(custom_app_context.hash('1234'))

It runs under python 3.9 with the following pip reqs:

py2exe
passlib==1.7.4

If I package it using the following py2exe script it works in py2exe 0.10.2.1 but it fails with the most recent py2exe version (0.11.1.1):

from distutils.core import setup
import py2exe #@UnusedImport

setup(
    console= [ { "script": "test.py",}, ],
    options = {"py2exe": {
        "packages": ['passlib'],
        "includes":['configparser'],
 } },
)

For some reason only a couple of files are added from passlib instead of the whole package

I see that the site module is excluded from the builds in hooks.py, and Py_NoSiteFlag and Py_NoUserSiteDirectory are set when initializing the interpreter. These lines predate the import into github, so I'm wondering if you have any insight into why this is the case (or if not, objections to including it). I suppose it makes some sense if the goal is to completely isolate the app from any python installed on the system, but with TortoioseHg, I'd like to be able to pip-install extensions to the user site directory and have that visible to the app. Additionally, importing site adds several things to __builtins__[1], which means Mercurial behaves slightly differently in some cases, depending on if it's built with py2exe or a different method. Opting into Py_NoSiteFlag and Py_NoUserSiteDirectory as a build time option seems fine, if you have compatibility concerns in the default case.
