Pyinstaller is not recognized as an external or internal command, an executable program or a command file

Question

I'm trying to compile a python program that prints "hello world." with the Pyinstaller module. But when I type the command pyinstaller HelloWorld.py in my command prompt, it told me "pyinstaller is not recognized as an internal or external command, an executable program or a command file". How can I make compilation works correctly?

Thank you !

In the HelloWorld.py file, I typed the following command:

print("Hello World !")

In the command prompt, I typed: pyinstaller HelloWorld.py

This is when I hit the "Enter" key that the error happens.

Answer 1

Simply you can install it using pip.

pip install pyinstaller

Requirements :

1. 3.7-3.11. Note that Python 3.10.0 contains a bug making it unsupportable by PyInstaller. PyInstaller will also not work with beta releases of Python 3.12.

2. PyInstaller should work on Windows 7 or newer, but it only officially support Windows 8+.

3. Support for Python installed from the Windows store without using virtual environments requires PyInstaller 4.4 or later.

4. Note that Windows on arm64 is not yet supported.
