How Can I Create Self-Contained Python Executables with PyInstaller?

Creating Self-Contained Python Executables

When distributing Python applications, it can be inconvenient to require users to install Python and dependencies. This article explores a solution to this problem: converting Python scripts into standalone executables.

PyInstaller: The Solution

PyInstaller is a powerful tool that enables users to bundle Python programs into single, portable executables. It is compatible with Windows, Linux, and Mac operating systems.

Quickstart Guide

To package your Python script using PyInstaller, follow these steps:

1. Install PyInstaller using PyPI: pip install pyinstaller
2. Navigate to the directory containing your program and run: pyinstaller yourprogram.py
3. This command generates a bundled executable in a "dist" subdirectory.

Advanced Options

To pack the executable into a single file, use the -F or --onefile parameter: pyinstaller -F yourprogram.py

If your program relies on side-packages, use the -p or --paths parameter to specify their location: pyinstaller -F --paths=Libsite-packages yourprogram.py

Additional Resources

For a comprehensive guide on using PyInstaller, refer to the official manual.

Troubleshooting

If you encounter import errors while running the executable, consider using the --hidden-import parameter to explicitly include necessary modules.
