Environment:

Python 3.8

Pyqt5

Mac OS X Catalina 10.15.6

I am trying to compile my python program in Mac OS application. I get this error message when I open the app:

(base) gb@MacBookGB % open dist/MyApplication.app                           
LSOpenURLsWithRole() failed with error -10810 for the file /Users/gb/myapp/dist/MyApplication.app.

I checked that files can be executed:

So I searched everywhere on the web to find solution but none worked. As I know Qt5 can make issue when compiling, I made a search and found your article: [https://doc.qt.io/qtforpython/deployment-pyinstaller.html](link url)

I decide to compile your python code shown in this article.

import sys
import random
from PySide2.QtWidgets import (QApplication, QLabel, QPushButton,
                               QVBoxLayout, QWidget)
from PySide2.QtCore import Slot, Qt

class MyWidget(QWidget):
    def __init__(self):
        QWidget.__init__(self)

        self.hello = ["Hallo Welt", "你好，世界", "Hei maailma",
            "Hola Mundo", "Привет мир"]

        self.button = QPushButton("Click me!")
        self.text = QLabel("Hello World")
        self.text.setAlignment(Qt.AlignCenter)

        self.layout = QVBoxLayout()
        self.layout.addWidget(self.text)
        self.layout.addWidget(self.button)
        self.setLayout(self.layout)

        # Connecting the signal
        self.button.clicked.connect(self.magic)

    @Slot()
    def magic(self):
        self.text.setText(random.choice(self.hello))

if __name__ == "__main__":
    app = QApplication(sys.argv)

    widget = MyWidget()
    widget.resize(800, 600)
    widget.show()

    sys.exit(app.exec_())

Then I run the command:

pyinstaller --name="MyApplication" --windowed MyApp.py

And I get exact same issue :

LSOpenURLsWithRole() failed with error -10810 for the file /Users/gb/myapp/dist/MyApplication.app.

I wonder if anyone already faced this issue and found a solution?

The -10810 error message seems to be a catch-all for errors in the executable file inside the app. For example, I have an app called Hello.app, and inside Hello.app/Contents/MacOS is a single executable script named Hello with two lines:

#!/bin/sh
osascript -e "display dialog \"Hello, world!\""

When I issue the command:

open Hello.app

or double-click the folder icon in Finder. I see the expected dialog box:

Hello World Dialog

However, when I introduce a syntax error:

osascript -e "display dialog "Hello, world!\""

the open command fails with the error message:

LSOpenURLsWithRole() failed with error -10810 for the file /full/path/name/of/Hello.app

To find the real error message, execute the program inside your app directly from the command line. In my case, the command is:

Hello.app/Contents/MacOS/Hello

and the much more informative error message is:

./Hello: line 2: unexpected EOF while looking for matching `"'

Of course, I have no idea what the actual error in your program is, but I hope this helps you find it!
