Can't create an Executable from Python Script using Pyinstaller on macOS Catalina

1. I Installed pyinstaller: pip install pyinstaller
2. Open terminal and typed : cd /Users/cn/PycharmProjects/Final_5/venv
3. pyinstaller --onefile main.py
4. then i moved the main.exe in the folder where all my dependencies are

Error I get :

Traceback (most recent call last):
  File "venv/main.py", line 4, in <module>
ModuleNotFoundError: No module named 'qtmodern'
[19444] Failed to execute script main

But everything is Installed, every module is installed. Why is it giving me this?
