Hi All
I am trying to use pyinstaller to make an .exe of my dash app.
I first did pip install pyinstaller which went well.
But when I run the pyinstaller command I get the error below.
I then tried to make a basic project (app.basic.py) holding only a simple
print('hallo') line to see if it was related to my dash app somehow but the
error was raised again.
What is causing this and how can I solve it :-)?
