Data Analysis with Python - Time Series Visualizer

Running the project gives

ModuleNotFoundError: No module named ‘matplotlib’

Running poetry install gives the following:

This is with the pre-configured pyproject.toml and poetry.lock files in boilerplate-page-view-time-series-visualizer.

You’ll need to post a link to a repl for a definitive answer but this appears to be the same error as all the scipy/pandas missing errors in the data analysis projects that have been posted of late in the forums.

I would uninstall all packages with the package tool and delete the poetry.lock file (in whichever order works), set python = ">=3.8,<3.12" in pyproject.toml, and reinstall seaborn, etc. as needed.
