Goodbye complicated installation instructions! Your users won’t even know they’re running a Python project because the Python Interpreter itself is bundled into your application. PyInstaller abstracts these details from the user by finding all your dependencies and bundling them together. As Raymond Hettinger often says in his excellent talks, “There has to be a better way.” This barrier to entry is way too high if your goal is to make an application available to as many users as possible. This has gotten much better in the last few years with the prevalence of wheels, but some dependencies still require C/C++ or even FORTRAN compilers! These problems explode if your user is lucky enough to get to the dependencies portion of the installation. Stop for a moment and consider if any of the above steps make any sense if you’re not a developer, let alone a Python developer. Download and install a specific version of Python.Think about what you typically go through when setting up a new machine for Python development. This roadblock stops users even before the installation guide delves into the complicated details of virtual environments, Python versions, and the myriad of potential dependencies. Often, the setup starts with opening a Terminal, which is a non-starter for a huge group of potential users. Setting up a Python project can be frustrating, especially for non-developers.

To fully appreciate PyInstaller’s power, it’s useful to revisit some of the distribution problems PyInstaller helps you avoid.įree Bonus: 5 Thoughts On Python Mastery, a free course for Python developers that shows you the roadmap and the mindset you’ll need to take your Python skills to the next level. PyInstaller gives you the ability to create a folder or executable that users can immediately run without any extra installation.

How to use PyInstaller on your own projects.

How PyInstaller can simplify application distribution.

In this tutorial, you’ll learn the following: This tutorial is for developers who want to distribute applications to users who may or may not be Python developers. There is much less information for developers building Python applications. There are countless tutorials on how to set up virtual environments, manage dependencies, avoid dependency pitfalls, and publish to PyPI, which is useful when you’re creating Python libraries.

Are you jealous of Go developers building an executable and easily shipping it to users? Wouldn’t it be great if your users could run your application without installing anything? That is the dream, and PyInstaller is one way to get there in the Python ecosystem.
