Nuitka is the optimizing Python compiler written in Python that creates executables that run without a separate installer. Data files can both be included or put alongside.
You can read more on the official website.
The install is easy with pip tool, then you can use this command.
python -m nuitka --help
Usage: python.exe -m nuitka [--mode=compilation_mode] [--run] [options] main_module.py
Note: For general plugin help (they often have their own
command line options too), consider the output of
'--help-plugins'.
Options:
--help show this help message and exit
--version Show version information and important details for bug
reports, then exit. Defaults to off.This python package need to have the Visual Studio Build Tools 2022 and need to use:
- Desktop development with C++
- MSVC v143 build tools
- Windows 10/11 SDK
- C++ CMake tools
- C++ ATL/MFC (optional but useful)
Let's install it.
I used this simple example:
import sys
from PyQt6.QtWidgets import QApplication, QLabel, QWidget, QVBoxLayout
def main():
app = QApplication(sys.argv)
window = QWidget()
window.setWindowTitle("PyQt6 + Nuitka Demo")
layout = QVBoxLayout()
label = QLabel("Hello! This is a PyQt6 application compiled with Nuitka.")
layout.addWidget(label)
window.setLayout(layout)
window.show()
sys.exit(app.exec())
if __name__ == "__main__":
main()Use this command to see all plugins:
nuitka --plugin-list
