Getting IOError: [Errno 21] Is a directory error when trying to run PyInstaller

I'm trying to create an executable file for my Python script using PyInstaller. I run in the terminal...

pyinstaller --onefile --windowed ./lab_attendant_emailer.py

From the directory that the python file is in. It starts running for a bit but returns this error.

Any help with what I'm doing wrong?

You might be run pyinstaller once and it creates dist directory.

When you try to rerun again, it has all directory structure created with previous command. Please cleanup your directory then rerun pyinstaller, that will work.
