[PyInstaller] ModuleNotFoundError: No module named 'pkg_resources.py2_warn'

[ttepperg]

Hi Guys,

I just updated my python 3.6 version to a more recent one, and suddenly I 
get the error:

ModuleNotFoundError: No module named 'pkg_resources.py2_warn'

when running a Mac App.

>From what I could find. apparently the problem is related to the version of
setuptools (was 45 before, is 46 now). According to the discussion here:

https://github.com/pypa/setuptools/issues/1963

A workaround is to compile the code with the flag:

hidden-import='pkg_resources.py2_warn'

And it actually works. However, I find this to be just an ugly solution and 
I was wondering
whether there is another way to solve this problem?

Cheers,

Thor.

[PyInstaller] Re: Pyinstaller cannot access a particular file

[Jamison Morse]

Hello Michael --

Have you found the solution to your issue? I am having the exact same issue 
and cannot figure out how to correct.

My info for the versions I am using is below:
408 INFO: PyInstaller: 3.6
409 INFO: Python: 3.8.2
409 INFO: Platform: Windows-10-10.0.18362-SP0

I get the same info:

line 37, in pywin32error
raise error(exception.winerror, exception.function, exception.strerror)
win32ctypes.pywin32.pywintypes.error: (1920, 'LoadLibraryEx', 'The file 
cannot be accessed by the system')


Any help would be appreciated. Thanks!

Jamison

[PyInstaller] Re: ModuleNotFoundError: No module named 'pkg_resources.py2_warn'

[bwoodsend]

There are a couple of others.

One is to put the following somewhere in your code:
import pkg_resources.py2_warn
Or to make it work as well with older setuptools versions:
try:
import pkg_resources.py2_warn
except ImportError:
pass

A more satisfactory solution would be to use PyInstaller's hooks which tell 
PyInstaller contain the hidden-import='pkg_resources.py2_warn' information. 
The hook for pkg_resources has been updated on github 

 
but the changes haven't been released yet. You could upgrade to the 
developer version on Github or you could manually update that file in your 
own installation.

Alternatively you can download that hook file and put it somewhere 
PyInstaller can find it (usually next to your main script).

[PyInstaller] Re: Compiling using pyinstaller external pythonpath that is in another program module

[António Alexandre Fraga Dias]

First thank you.

I think i have done it correctly, the adding of the path that you 
suggested. You can see the file.



# -*- mode: python ; coding: utf-8 -*-


block_cipher = None




a = Analysis(['PC.py'],
 pathex=['D:\\Python\\Novo\\Point Cloud Ver2','C:\\Program 
Files\\CARIS\\BASE Editor\\5.3\\python\\3.5'],
 binaries=[],
 datas=[('ReadAPointCloudFromAPLYFileExample_01.png', '.')],
 hiddenimports=[],
 hookspath=[],
 runtime_hooks=[],
 excludes=['caris'],
 win_no_prefer_redirects=False,
 win_private_assemblies=False,
 cipher=block_cipher,
 noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
 cipher=block_cipher)
exe = EXE(pyz,
  a.scripts,
  [('v', None, 'OPTION')],
  exclude_binaries=True,
  name='Point Cloud',
  debug=False,
  bootloader_ignore_signals=False,
  strip=False,
  upx=True,
  console=True , icon='Point_Cloud.ico')
coll = COLLECT(exe,
   a.binaries,
   a.zipfiles,
   a.datas,
   strip=False,
   upx=True,
   upx_exclude=[],
   name='Point Cloud')


After running it the result was the same. I have to had that the 
path C:\\Program Files\\CARIS\\BASE Editor\\5.3\\python\\3.5 is a variable 
path since it corresponds to the install directory and I retrieve it using 
a class.
In a way i have also to refer that the caris module has DLL hidden in the 
pyd, do not know if this is the reason for having this error. It's clear 
when running without the 
--exclude-module=caris

command.

If i do it i get the DLL list that pyinstaller sees but does not finds it. 
Any ideas?
