Adding textfile with --onefile option - python-3.x

Question

the --add-data option works well without using --onefile option
I want the data text files to be compressed and merged into an exe file. But exe file only works when the data text file is in the same folder.
How can I merge the text file into the only one exe file??
When I used:
pyinstaller --add-data ="\GameUserSettings.ini;." file.py
it works.
pyinstaller --onefile --add-data ="\GameUserSettings.ini;." file.py
it can make the file.exe but it doesn't work well. and it works only when the text file is in the same folder.

Answer 1

When you add your text file with one-dir, Pyinstaller would put your file next to your executable and you will be fine when accessing your file by the script (e.g open("myfile.txt"). But when you create your executable with --onefile it would extract your file in a temp directory which is a separate directory, so calling open("myfile.txt") would result in a NotFound error because the file doesn't exist besides your executable. So you need to change the path to point to the temp directory. The sys._MEIPASS would return the temp directory so you need to locate your files inside it. You can find more info in here.
A function like this would solve the problem:
import sys
import os
def resource_path(relative_path):
if hasattr(sys, '_MEIPASS'):
return os.path.join(sys._MEIPASS, relative_path)
return os.path.join(os.path.abspath("."), relative_path)
Then you can access your file with source = resource_path("myfile.txt").
