How can I build a working exe file using Pyinstaller if I use third-party libraries?

Question

Python

All good!
I'm trying to compile my scripts to exe.
In scripts I use third-party libraries (flask and pyserial). The project itself consists of two files: the first is a large class (api manager) and the second is the one that needs to be launched, in which I import the first script + flask. The project structure is as follows:

-project
    -api.py
    -to_run.py

Everything compiles fine, with the command pyinstaller.exe --onefile --windowed --icon=app.ico to_run.py But
then the finished executable doesn't run : filed to execute script simple script with print("Hello Word!") - everything works fine. Please tell me how to solve this problem

Answer 3

First, add "main.py" at the end of the line. And you, most likely, did not add some files required by the script. Then you will have a default spec file. In his Analysis section, add other scripts after main.py, and in datas in brackets ('File_name', 'folder_where_this_file'). For example, for me it was datas=[('data/Settings.txt', 'data'), ('data/CossacksPlayers.json', 'data'), ('images/LogoLOP.png', 'images'), ('LOfP.ico', '.')]
