pyinstaller Hidden import not found

I'm using pyinstaller. In my script there is:

import toml


config = toml.load('config.toml')

I compiled my script with:

pyinstaller main.py --onefile --clean --name myApp

but when I run the executable it gave me: ModuleNotFoundError: No module named 'toml'

So I tried this:

pyinstaller main.py --hidden-import toml --onefile --clean --name myApp

and now pyinstaller says: ERROR: Hidden import 'toml' not found

Solution

  • Found the answer. If you are using a virtual environment (Like Pipenv, pyenv, venv) you need to run pyinstaller in the context of that environment. So...

    pip install pyinstaller
python -m PyInstaller main.py ....

    Also, as mosegui pointed out, you should put your config flags before the file name:

    pyinstaller --hidden-import toml --onefile --clean --name myApp main.py

    though this was so long ago that I'm not sure if that was actually an issue for me.

    These days I use Poetry so once I have a Poetry environment I just poetry shell and/or poetry run pyinstaller .... Anytime you use poetry run <some cmd sequence> it runs whatever your command sequence is in the context of the current virtual environment. I believe pipenv run accomplishes a similar thing but Poetry always works better for me.
