I am trying to create a .exe file to run a python dashboard created with Plotly Dash. Once I create the file with PyInstaller and try to run it, I get this error:

I’m new to coding, and I can’t figure out why it can’t find the dcc dependency. Is there a better way to compile my modules into one executable file?

I have a few python modules and excel files in the same directory as well as an -asset folder with images and css files.
