Pyinstallar doesn't create .exe file

Question

I'm trying to create an executable file for a simple 'Hello World' python code. I'm using an Ubuntu Subsystem in Windows 11 and I'm trying to create the .exe file with the command:

pyinstaller --onefile Test.py

The command runs and creates folders "build" and "dist", but it doesn't create the .exe file inside the "dist" folder as it should do.

In the terminal I have the fallowing message:

It is weird because I tried the same thing a week ago and the .exe was created normally. I even tried unistalling and reinstalling the pyinstaller library, but still got the same results.

Answer 1

Since you're creating an executable under WSL, a Linux environment, your output executable would be that of a Linux binary instead of a Windows .exe file.

Linux binary do not an extension, but they will still be properly run if you run the path to the binary file under your WSL shell (e.g. ./path_to_binary/binary_file)

If you wish to create an executable for Windows, the simplest way is to run the same code with pyinstaller on Windows itself rather than the WSL shell.
