The first time you run PyInstaller on your app, PyInstaller will generate a spec file from scratch and populate it with some sane defaults. spec, this file includes details about how your Python app needs to be packed up. (More on this later.)Īfter analyzing your code and discovering all of the libraries and modules it uses, PyInstaller then generates a “spec file.” A Python script with the extension. PyInstaller can detect and automatically package many common Python packages, like NumPy, but you might need to provide hints in some cases. For instance, if your program’s entry point is myapp.py, you would run pyinstaller myapp.py to perform the analysis.
PyInstaller reads in your program from its entry point. PyInstaller works by reading your Python program, analyzing all of the imports it makes, and bundling copies of those imports with your program.
PyInstaller can be installed in your default Python installation, but it’s best to create a virtual environment for the project you want to package and install PyInstaller there. PyInstaller is a Python package, installed with pip ( pip install pyinstaller). In this article we’ll explore the basics of using PyInstaller including how PyInstaller works, how to use PyInstaller to create a standalone Python executable, how to fine-tune the Python executables you create, and how to avoid some of the common pitfalls that go with using PyInstaller.
