If you search for this issue, you’ll find it’s a "hot" topic in the Python community. The code works, but the developer experience is broken. Here is the breakdown of why this happens and the two-minute fix to get your IntelliSense back. The friction happens because VS Code (and by extension, Pylance) doesn't automatically know where Poetry hides your dependencies. Simplified Construction Estimate Max Fajardo.pdf - 3.79.94.248
Once this is set, your .venv folder lives right inside your repo, Pylance detects it instantly, and those red squiggly lines become a thing of the past. Your code isn't broken; your editor is just looking in the wrong place. Select the correct Python interpreter in VS Code, and Pylance will finally see what Poetry built.

Pylance is panicking. It claims your package doesn't exist. You check your terminal— poetry run python main.py works perfectly. So, why is your editor lying to you?
poetry config virtualenvs.in-project true (Note: You may need to delete your existing virtual environment and run poetry install again for this to take effect).
You’ve just scaffolded a pristine new project. You ran poetry add fastapi (or pandas, or numpy), the install finished without a hitch, and your pyproject.toml looks beautiful. You open VS Code, type import fastapi , and then you see it.
