error No module named 'img2pdf' when executing .exe - pyinstaller

Question

I'm am trying to build an .exe file with pyinstaller. When launching the build .exe file I have the following error :

ModuleNotFoundError: No module named 'img2pdf'

I have already build some .exe with pyinstaller, which are working. So I guess the problem is not pyinstaller. I am also using Pycharm with a virtual environnement.

The code is working well when running on Pycharm.

With the --debug all option of pyinstaller, I can see the following lines :

img2pdf not found in PYZ Traceback (most recent call last): File "download_pdf.py", line 7, in File "

importlib._bootstrap>", line 983, in _find_and_load File "", line 965, in _find_and_load_unlocked ModuleNotFoundError: No module named 'img2pdf' [4812] Failed to execute script download_pdf

I tried pip install img2pdf in the Terminal of pycharm (virtual environnement) and in the command prompt of my OS (windows 10).

Does anyone know what's wrong ?

Answer 1

I had to use the following option of pyinstaller : --hidden-import=img2pdf

It now works.
