Pyinstaller "Failed to script execute main" problem

Question

Edit: Python 3.7.4, Windows 10

Edit2: I found the reason for the error. output:

Traceback (most recent call last):
 File "myMain.py", line 2, in <module>
 File "c:\users\faruk\appdata\local\programs\python\python37\lib\site- 
packages\PyInstaller\loader\pyimod03_importers.py", line 627, in exec_module
exec(bytecode, module.__dict__)
 File "site-packages\PyQt5\__init__.py", line 41, in <module>
 File "site-packages\PyQt5\__init__.py", line 33, in find_qt
ImportError: unable to find Qt5Core.dll on PATH
[13936] Failed to execute script myMain

Here is the solution: https://stackoverflow.com/a/56962128/9377945

I am trying to convert my py files to exe with pyinstaller.

My sample code is here:

import sys
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QLabel, QGridLayout, QWidget
from PyQt5.QtCore import QSize    

class HelloWindow(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)

        self.setMinimumSize(QSize(640, 480))    
        self.setWindowTitle("Hello world") 

        centralWidget = QWidget(self)          
        self.setCentralWidget(centralWidget)   

        gridLayout = QGridLayout(self)     
        centralWidget.setLayout(gridLayout)  

        title = QLabel("Hello World", self) 
        title.setAlignment(QtCore.Qt.AlignCenter) 
        gridLayout.addWidget(title, 0, 0)

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    mainWin = HelloWindow()
    mainWin.show()
    sys.exit( app.exec_() )

I used this code for convert:

pyinstaller main.py --noconsole

When I tried to run exe file, I got 'Failed to execute script main' error.

I tried and cmd opened and closed. I added extra one parameter -w and got same error. — ImC0der, Sep 15 '19 at 13:54
Try changing the module name, for example to `myMain.py` and run `pyinstaller -c -F myMain.py` again. Report the result. — S. Nick, Sep 15 '19 at 13:59

Remove pyinstaller and PyQt5 and then install them with using pip3

pip3 install pyinstaller   
pip3 install PyQt5

have you installed those packages? if you're using an IDE for coding, you have to install your packages in your system too

I am using Vscode, virtualenv and my packages(only pyqt5) installed. Code works nice before convert. – ImC0der Sep 15 '19 at 13:32
are you using windows? you must install pyqt5 in your windows system too. (command prompt) – Virtual Dreamer Sep 15 '19 at 13:39
I am using windows. pyqt5 only installed in virtualenv. I will try it – ImC0der Sep 15 '19 at 13:47
Nothing changed. Same error. – ImC0der Sep 15 '19 at 13:51
