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). #No module named pyinstaller how toIn 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. PyInstaller doesn’t make the process of packaging a Python app to go totally painless, but it goes a long way there. The most popular solution of the bunch, and the most mature, is PyInstaller. Several third parties have engineered solutions for deploying standalone Python apps. But the surging popularity of Python has created greater demand for running Python apps on systems with no installed Python runtime. Python programs have, by and large, been run in-place on systems where a copy of the Python interpreter lived. To be fair, the original use case for Python never called for standalone packages. For one, Python provides no native mechanism for compiling a Python program into a standalone executable package. Python, powerful and versatile as it is, lacks a few key capabilities out of the box.
