I try to turn a .py file into a .bin file with Nuitka. Since it have to work on machine without python installed, I use the --standalone option that comes with --follow-imports and --python-flag=no_site options to import my modules. I use --onefile too, if I understand well, this option makes folders useless (only the .bin is necessary). So I use the command: python3 -m nuitka --standalone --follow-imports --python-flag=no_site --onefile myscript.py. The command works and I have my .bin (plus 3 folders (.build, .dist, .onefile-dist)). I try to execute my program: ./myscript.bin with the head: #!/usr/bin/python3 from pathlib import Path from cryptography.fernet import Fernet import subprocess import math from math import gcd and I got a "No module named" error, but only on the second import I do. I conclude Nuitka import correctly the first package, so the .bin works as well as the .py on this point, but don't import this second package like the .py does. Looking for similar problems on the Internet, I only found differences between the versions of Nuitka and the package versions as follows. But when I use python3 --version and nuitka --version, I got this: Python 3.12.3 and 2.7.2 Commercial: None Python: 3.12.3 (main, Feb 4 2025, 14:48:35) [GCC 13.3.0] Flavor: Debian Python Executable: ~/venv/bin/python3 OS: Linux Arch: x86_64 Distribution: Linuxmint (based on Ubuntu) 22 Version C compiler: /urs/bin/gcc (gcc 13). We can see the same Python version for both so it's not the problem. In this case, what is the problem? Are there some modules that we just can NOT import in the .bin? I specify that I'm on a Linux Mint 22 VM and in a virtual environment (create with python -m venv venv) because it was necessary to use pip to install (and in result use) Nuitka. Try to execute the .bin in or out the venv give the same result. Continue reading...
