Executable from Pyinstaller works when launching in terminal, but not by double clicking

🎈 Using Streamlit
, ,
1

I have main.py:

import streamlit as st

st.text("This program is running")

And wrapper.py in the same dir:

import subprocess

subprocess.run(["streamlit", "run", "main.py"])

When I run the command pyinstaller --onefile --clean -w --add-data "main.py;." wrapper.py, an executable is created (without errors), and I can run this executable as .\dist\wrapper.exe, but when I double click it (in Windows), I get the following error:

Traceback (most recent call last):
  File "wrapper.py", line 9, in <module>
  File "subprocess.py", line 548, in run
  File "subprocess.py", line 1024, in __init__
  File "subprocess.py", line 1493, in _execute_child
FileNotFoundError: [WinError 2] The system cannot find the file specified

I have checked quite a few other posts in the forum about this topic, but couldn’t find a solution for my specific case. Does anyone have an idea?
