--noconsole not working with Pyinstaller

Question

When I run my program using python myprogram.py , it runs as intended and no command prompt pops up. When I create an executable using pyinstaller myprogram.py -F --noconsole , a blank command prompt pops up. The title of this command prompt is the location of the wkhtmltopdf.exe program used within myprogram.py. I don't think the issue is with wkhtmltopdf though since the command prompt doesn't show up when I run python myprogram.py . I think it's something with pyinstaller, but I thought using the --noconsole option would prevent this. I've also tried --windowed.

Answer 1

When you run PyInstaller on your project, does a .SPEC file also appear?

If so, edit the .SPEC file's exe field like so:

exe = EXE(
      ...,
      console=False,
      ...
      )

Then run PyInstaller on the .SPEC file.

If a .SPEC file didn't appear before, try running PyInstaller on your project without any parameters (so just pyinstaller myProgram.py ). A .SPEC file should appear and you can edit it as above and then rerun PyInstaller.

Here is my suggestion on this: comment out all print statements. Keep it simple, like so:

pyinstaller --onefile  --noconsole <filename>.py

Answer 3

I was having lots of trouble getting the noconsole or windowed options to work on my Windows 10 machine.

I started with the .spec file generated by PyInstaller.
Somehow it had the line: [('v', None, 'OPTION')], in the EXE section.
When I commented that out, and added the nonconsole and windowed options, it worked!
Here is the working section:

       a.scripts,
       # [('v', None, 'OPTION')],
       exclude_binaries=True,
       name='my program name',
       debug=False,
       bootloader_ignore_signals=False,
          strip=False,
          upx=False,
          console=False,
          windowed=True)

I can only guess that the offending line stopped PyInstaller from processing the rest of the EXE statement, and so it missed the options.
