Answer 1

I hope this helps someone:

C:\Users\%user_name%\AppData\Local\Programs\Python\Python36-32\Lib\site-packages\selenium\webdriver\common

Add import and change in "def start":

from win32process import CREATE_NO_WINDOW

    try:
        cmd = [self.path]
        cmd.extend(self.command_line_args())
        self.process = subprocess.Popen(cmd, env=self.env,
                                        close_fds=platform.system() != 'Windows',
                                        stdin=self.log_file, stdout=self.log_file, stderr=self.log_file, creationflags=CREATE_NO_WINDOW)
    except TypeError:
        raise

if error, check pywin32: pip install pywin32

Answer 2

after some search I found the full solution : Firstly go to -

C:\Python35\Lib\site-packages\selenium\webdriver\common\service.py

Change :

self.process = subprocess.Popen(cmd, env=self.env,
                                            close_fds=platform.system() != 'Windows',
                                            stdout=self.log_file, stderr=self.log_file)

To:

self.process = subprocess.Popen(cmd, stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=False, creationflags=0x08000000)

now simply build your app.py like this:

pyinstaller --noconsole --onefile  --noupx   Yourfile.py

Firstly go to- C:\Python35\Lib\site-packages\selenium\webdriver\common\service.py

then in def start(self):

def start(self): """ Starts the Service.

    :Exceptions:
     - WebDriverException : Raised either when it can't start the service
       or when it can't connect to the service
    """
    try:
        cmd = [self.path]
        cmd.extend(self.command_line_args())
        self.process = subprocess.Popen(cmd, env=self.env,
                                        close_fds=platform.system() != 'Windows',
                                        stdout=self.log_file,
                                        stderr=self.log_file,
                                        stdin=PIPE,
                                        creationflags=0x08000000)``

Just add creationflags=0x08000000 , I've already added there in the code. creationflags is a constant. It will work fine.

or, you might also replace it with creationflags=CREATE_NO_WINDOW and add this line code from win32process import CREATE_NO_WINDOW.

In my case, first method was working.
