Jul 26, 2024 · PyInstaller hooks are Python scripts that provide instructions to PyInstaller about how to package specific modules or packages. These hooks are crucial for ensuring that all necessary files, such as data files, hidden imports, and other resources, are included in the final executable.
PyInstaller reads a Python script written by you. It analyzes your code to discover every other module and library your script needs in order to execute. Then it collects copies of all those files – including the active Python interpreter! – and puts them with your script in a single folder, or optionally in a single executable file.
In this step-by-step tutorial, you'll learn how to use PyInstaller to turn your Python application into an executable with no dependencies or installation required. This is great if you want to distribute applications to users who may or may not be Python developers.
In the most simple case, set the current directory to the location of your program myscript.py and execute: PyInstaller analyzes myscript.py and: Writes myscript.spec in the same folder as the script. Creates a folder build in the same folder as the script if it does not exist. Writes some log files and working files in the build folder.

Here are seven examples, of roughly increasing complexity, that demonstrate how to package python applications using the basic commands of PyInstaller. The later examples also demonstrate how to package a basic Kivy GUI app.
We recommend that this code is run inside a virtual environment.
•Linux or macOS (Tested on Ubuntu 14.04 and High Sierra)
•Python (Tested on Python 2.7 and 3.4)
•PyInstaller
•Numpy (To test non-standard library imports)
•Pandas (To process a csv file)
1.Download this repository
2.Install the requirements
3.Navigate to the app folder
4.Have a look at the files inside the app folder to see what they do
•The examples are all kept very short and basic
5.Run the corresponding PyInstaller command
App1 - Simplest app with standard importApp2 - Import a function from another scriptApp3 - Include a single data fileApp4 - Include folders of dataApp5 - Simple single file Kivy appApp6 - Kivy app with a separate kv fileThe commands above produce two folders and a .spec file:
•The build folder contains temporary files that were used whilst the application was being built
•The dist folder contains the application itself, which can now be distributed to other users
•The .spec file tells PyInstaller how to process your script (see reference 2 for further info)
At run-time, the app will create a temporary folder to store data and binary files. The path to this folder can be accessed by the environment variable _MEIPASS (only at run-time).
Use venv to create as many different development environments as you need, each with its unique combination of Python and installed packages. Install PyInstaller in each virtual environment. Use PyInstaller to build your application in each virtual environment. Note that when using venv, the path to the PyInstaller commands is: Windows: ENV ...

May 25, 2019 · PyInstaller can be used to create .exe files for Windows, .app files for Mac, and distributable packages for Linux. Optionally, it can create a single file which is more convenient for distributing, but takes slightly longer to start because it unzip itself.
