Install.py

As projects grew more complex, setup.py evolved into setuptools . However, running a raw .py file for installation had risks. It executed arbitrary code on your machine with full permissions—a "long story" that often ended in broken system Python installations.

In the early days of Python, installing a library wasn't as simple as a single command. Developers relied on a module called distutils . To install a package, you would download the source code, navigate to the folder in your terminal, and run the legendary command: python setup.py install install.py

While largely deprecated for general libraries, you will still find install.py in specific, specialized corners of the tech world: As projects grew more complex, setup

This script, often essentially a rename of the concept of an "install.py," was the gatekeeper. It would check your system for a C compiler, look for dependencies, and then physically move files into your Python's site-packages folder. The Evolution: From Scripts to Tools In the early days of Python, installing a

To solve this, the community moved toward . Instead of running an installation script every time, developers pre-built the software into a "wheel" file. Now, when you run pip install , it rarely executes an install.py script anymore; it simply unpacks the pre-built files into the right place. The Legend Today: Where install.py Lives On
