A package I installed into my virtual environment (webargs) gives a "module not found" ImportError even though it is installed.

After making a virtualenv following the guide, I installed flask, flask-restful and webargs, which my app uses. I installed all three the same way through the bash with pip install but only webargs is failing. I even tried to install it again by manually going to the Web tab and then "open bash in this virtualenv" but it understandably told me "requirement already met".

Edit: note that if I enter a console inside the virtualenv (directly from the link in the Web tab) and run $python from there, importing webargs works.

Edit 2: I managed to fix it by fiddling with the path added to sys.path somehow. Consider this resolved.

Cool. Glad you worked it out.

You need to install the package that provides the "flask_uploads" module.

what is the package please? I have been trying to get through this error since morning but haven't resolve it till now

Probably this one: https://pypi.org/project/Flask-Uploads/

It has already been installed, but I tried again to confirm and I got the message below <br><br> $ pip install Flask-Uploads Defaulting to user installation because normal site-packages is not writeable Looking in links: /usr/share/pip-wheels Requirement already satisfied: Flask-Uploads in /home/commerce/.local/lib/python3.10/site-packages (0.2.1) Requirement already satisfied: Flask>=0.8.0 in /home/commerce/.local/lib/python3.10/site-packages (from Flask-Uploads) (2.2.2) <br><br> The message below is from server error <br><br> Error running WSGI application 2023-05-04 08:58:01,488: ModuleNotFoundError: No module named 'flask_uploads' 2023-05-04 08:58:01,488: File "/var/www/commerce_pythonanywhere_com_wsgi.py", line 16, in <module> 2023-05-04 08:58:01,488: from main import app as application # noqa 2023-05-04 08:58:01,489: 2023-05-04 08:58:01,490: File "/home/commerce/FlaskEcommerce/main.py", line 5, in <module> 2023-05-04 08:58:01,490: from flask_uploads import UploadSet, configure_uploads, IMAGES, patch_request_class
