Before typing random commands, it’s crucial to understand why this breakage occurs. Pylance is a static type checker. It needs to know the exact Python interpreter and site-packages path to validate your imports. Poetry, by default, is "non-intrusive." It creates virtual environments in a cache directory (e.g., ~/Library/Caches/pypoetry/virtualenvs/ on macOS or %APPDATA%\pypoetry\virtualenvs on Windows).
VS Code, however, looks for virtual environments in standard locations (like the project root’s .venv, venv, or env folder). When these two paradigms collide, Pylance throws the reportMissingImports error.
If you want VS Code to automatically detect the Poetry virtual environment without manual path selection every time, you can force Poetry to create the venv inside your project. pylance missing imports poetry hot
Run this command in your terminal:
poetry config virtualenvs.in-project true
Now, delete your old env (poetry env remove --all) and reinstall (poetry install). A .venv folder will appear in your project root. Before typing random commands, it’s crucial to understand
Why this is hot: VS Code automatically detects a .venv folder in the root. Pylance will immediately find your imports. The only downside is that you commit .venv to .gitignore.
You’ve embraced modern Python development. You use Poetry for dependency management and virtual environments because you’re tired of the requirements.txt chaos. You use VS Code with Pylance because you want blazing-fast type checking and autocompletion. Now, delete your old env ( poetry env
Yet, here you are. Your pyproject.toml is pristine. poetry install runs without a hitch. The script executes perfectly when you type poetry run python script.py. But in your editor, the squiggly red lines are mocking you.
Error: Import "x" could not be resolved. Pylance(reportMissingImports)
You are experiencing the "hot" pain point of the modern Python stack: Pylance cannot see the virtual environment that Poetry created.
This article is the definitive guide to understanding why this happens and, more importantly, how to fix it permanently.
