I encountered this error when converting my “app.py” file into executable file by using pyinstaller app.py –onefile.

14907 WARNING: Execution of ‘copyfile’ failed on attempt #1 / 20: PermissionError(13, ‘Permission denied’).
RuntimeError: Execution of ‘copyfile’ failed – no more attempts left!

I’m only trying to run a simple mouse and keyboard controls with this code:

import pyautogui
import time

pyautogui.hotkey("win", "r")
pyautogui.write("notepad")
pyautogui.hotkey("enter")
time.sleep(1)
pyautogui.moveTo(500, 300, 1)
pyautogui.write("Hello World!", .500)
pyautogui.press("t", 2, 1)
pyautogui.press("e", 2, 1)
pyautogui.press("s", 2, 1)
pyautogui.press("t", 2, 1)
