compilation and console

[Itsik Weissman]

I have a script ‘mysoft.py’.

Compiling it with ‘pyinstaller –F –i icon.ico mysoft.py’ gives a good executable. It runs fine.

Compiling it with  ‘pyinstaller –F –w –i icon.ico mysoft.py’ gives a bad executable. When launching it, I get an error message “mysoft.py script failed to execute”.

Any idea how to fix this?

Are you using subprocess anywhere (possibly indirectly through a dependency)? That’s the only case I know of where --windowed leads to breakages. It’s also worth verifying that pythonw mysoft.py works.

Thank you

I was actually using subprocess.

You can get around it by explicitly setting unused pipes to subprocess.DEVNULL rather than letting them default to inheriting an invalid pipe. So if you were using:

from subprocess import run, PIPE

run(["echo", "hello"], stdout=PIPE)

you should explicitly redirect the unused stdin and stderr to NULL:

from subprocess import run, PIPE, DEVNULL

run(["echo", "hello"], stdout=PIPE, stdin=DEVNULL, stderr=DEVNULL)

I was actually using

current_machine_id = subprocess.check_output('wmic csproduct get uuid')
