You might need to make sure you’re using the same version of Python and project dependencies as you have deployed somewhere. Those versions might be different than your system version. Keeping your project dependencies isolated also encourages you to document your dependencies (e.g. in requirements.txt), which is essential for reproducibility. If you have every package from every project installed globally then you tend to end up having issues when you or someone else tries to install a project in a different environment (the classic “I don’t know what’s wrong on your machine but it works fine on my mine”).
