Pyinstaller "ValueError: Can't mix absolute and relative paths" - python-3.x

Question

I am using windows 10 and anaconda3 to manage my python packages. This is my first time to use python, and I'm trying to make my own gui program with pyqt5. Also I'm trying to make .exe file using Pyinstaller. The issue I am running into is that the .exe is throwing the error block:
(pyqt5_env) C:\Python Projects>pyinstaller -w -F App_ver05.py
268 INFO: PyInstaller: 4.0.dev0+b3dd91c8a8

ValueError: Can't mix absolute and relative paths
The same error occurs regardless of which .py file is used. For information, I wrote the used code below.
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QVBoxLayout
class MyApp(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
btn1 = QPushButton('&Button1', self)
btn1.setCheckable(True)
btn1.toggle()
vbox = QVBoxLayout()
vbox.addWidget(btn1)
self.setLayout(vbox)
self.setWindowTitle('QPushButton')
self.setGeometry(300, 300, 300, 200)
self.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = MyApp()
sys.exit(app.exec_())
I uninstalled and reinstalled pyinstaller but it didn't work. I don't think its a code issue because the code is really simple. Can anyone give a solution or hint for this problem?

Answer 1

What happened for me is that the absolute path name had a space in it. Once the project was moved to a directory without spaces it was able to build

Answer 2

The solution of this problem is to use the full file name and append the flag -F to the file name. In your case for example if for the file App_ver05.py the absolute path is :
/home/user123/Desktop/foldername/App_ver05.py
Then use the command :
pyinstaller -F /home/user123/Desktop/foldername/App_ver05.py
