Description

Describe the problem I'm having problems whenever I use the --noconsole flag. When I create the executable just using --onefile everything works correctly, however, the terminal opens every time I run the .exe executable (which is a problem). I hope you can help me with this problem, I'll leave the image of the error that occurs whenever I have to run the executable created with the --noconsole flag.

  • OS: windows 11
  • Browser chrome

UPDATE 1: I created a simple project from scratch with just the eel library, a single python file and a simple html file and when using --noconsole the same problem I described in the image above occurred, which leads me to believe that it is an error in the Library. I need urgent help, because I bet all the development of my project on this library. Thank you for any help.

UPDATE 2: I managed to work around the problem but not solve it. I used the following:

import os
import sys

f = open(os.devnull, 'w')
sys.stdout = f
sys.stderr = f

Research direction
Investigate how Eel configures PyInstaller settings, particularly the noconsole flag. Look at the Eel build process in the codebase, likely in setup.py or related scripts. The error image suggests a crash when the flag is used; check for any missing dependencies or incorrect path handling when console is hidden. Also examine the workaround provided by the user (redirecting stdout/stderr) to see if it can be incorporated as a fix.
