I am attempting to package my app for windows but I keep getting this error when running the .exe file generated. The file does exist in the project directory and it works fine when running main.py directly. In my main.py I called Builder.load_file('home_screen.kv'), which is where it seems to be throwing the error.
Traceback (most recent call last):
File "main.py", line 46, in <module>
File "site-packages\kivy\app.py", line 800, in run
File "main.py", line 10, in build
File "main.py", line 15, in __init__
File "site-packages\kivy\lang\builder.py", line 288, in load_file
FileNotFoundError: [Errno 2] No such file or directory: 'home_screen.kv'
[3208] Failed to execute script main
This problem is not specific to home_screen.kv since even if I remove that line the following line, Builder.load_file('create_schedule.kv'), throws the same error.
In your .spec file add a line in the Analysis like:
datas=[('*.kv', '.')],
This will include the home_screen.kv (assuming it is in the same directory as your main.py).
