[SOLVED] How can I use Nuitka to import all script's modules?

How can I use Nuitka to import all script's modules?

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.

Edit: I also try with Pyinstaller/auto-py-to-exe and cx_Freeze in the same conditions but I got the same result.

Solution

I finally found out.

Native modules aren't the same in and out the venv. In that case, cryptography is native to Python out the venv but not in. Since we are in the venv, try a pip install cryptography works, and if we retry the Nuitka command, the imports work correctly, and the excusion of the .bin created too, even in an environment without Python or cryptography.
