Packaging with nicegui-package makes process hang about nicegui HOT 12 CLOSED

I tried on a windows 10 virtual machine (my machine is windows 11) and it also does not currently work. I also tried running with admin but still have no luck.

from nicegui.

Also when left on it seems to make a LOT more processes of itself.

One thing to note is that I did build pyinstaller from the bootloader I will try without right now too.

Still doesn't work with prebuilt.

Hi @KDot227,

Have you read https://nicegui.io/documentation/section_configuration_deployment#package_for_installation?

Just make sure to call ui.run with reload=False in your main script to disable the auto-reload feature.

Using reload=True (the default) might cause a hanging process.

Just tried with it set to False and it still isn't working.

I was able to build and run the provided example natively on Windows 10 with Python 3.12. I only changed the following line:

ui.run(storage_secret="THIS_NEEDS_TO_BE_CHANGED", reload=False, port=8882)

I only changed the port because of a conflict on my system. Note: the command is actually nicegui-pack.

@KDot227, I should have mentioned I did this with both PyInstaller and NiceGUI running in a venv. You could see if that works. Here is my generated spec file for reference:

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


a = Analysis(
    ['d2.py'],
    pathex=[],
    binaries=[],
    datas=[('F:\\a\\dev\\python\\pyinstaller_test\\venv\\Lib\\site-packages\\nicegui', 'nicegui')],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    noarchive=False,
    optimize=0,
)
pyz = PYZ(a.pure)

exe = EXE(
    pyz,
    a.scripts,
    [],
    exclude_binaries=True,
    name='Your App Name',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    console=True,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
)
coll = COLLECT(
    exe,
    a.binaries,
    a.datas,
    strip=False,
    upx=True,
    upx_exclude=[],
    name='Your App Name',
)

Hope this helps.

I'm going to try using a different port and see if that works.

from nicegui.

didn't change anything. Will try your spec file now then if that doesn't work I'll make a venv.

from nicegui.

It's working with your spec file now. Not too sure why but I'm not complaining.

thank you @afullerx
