I am trying to compile my application on the poetry environment where I am building the package.

Here is the spec file. This same spec file compiles fine via GitHub actions but fails on my poetry environment.

# -*- mode: python ; coding: utf-8 -*-
from PyInstaller.utils.hooks import copy_metadata
import sys
sys.setrecursionlimit(5000)

datas = []
datas += copy_metadata('pkg', recursive = True)

a = Analysis(
    ['app.py'],
    pathex=[],
    binaries=[],
    datas=[],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    noarchive=False,
    optimize=0,
)
pyz = PYZ(a.pure)

exe = EXE(
    pyz,
    a.scripts,
    a.binaries,
    a.datas,
    [],
    name='pkg',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    upx_exclude=[],
    runtime_tmpdir=None,
    console=True,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
)

When I run the command pyinstaller --clean app.spec , it gives me this warning which makes me think that pyinstaller is not able to fine some dependencies in the virtual environment.

219 WARNING: Assuming this is not an Anaconda environment or an additional venv/pipenv/... 
environment manager is being used on top, because the conda-meta folder
C:UsersXXXXAppDataLocalpypoetryCachevirtualenvsvenvconda-meta does not exist.

Would greatly appreciate any suggestions to fix this. Below is the ImportError I get in the window of the compiled executable.

I included setuptools in my poetry dependencies as per a stack overflow suggestion, but didn’t help.
