You need to tell VS Code to use the Python executable inside Poetry's virtual environment.
Sometimes the environment exists, but the internal structure Pylance needs is missing.
Before we fix it, we must understand the enemy. Pylance is a language server that needs to know exactly where your Python interpreter and site-packages live.
When you use poetry install, Poetry creates a virtual environment, usually hidden outside your project folder (e.g., ~/Library/Caches/pypoetry/virtualenvs/ on Mac, or %APPDATA%\pypoetry\virtualenvs on Windows).
The conflict: Pylance defaults to looking for the Python interpreter at the system level or the root of your workspace. Since the Poetry venv is "hidden," Pylance ignores it, leading to false-positive missing imports errors.
The integration of Pylance and Poetry can significantly enhance your Python development experience. By following these steps, you should be able to resolve issues related to missing imports and ensure a smoother workflow. If issues persist, consider checking the documentation of both tools or seeking help from their communities. pylance missing imports poetry hot
When Pylance reports missing imports while using Poetry in VS Code, it is typically because Pylance is looking at a different Python interpreter than the one Poetry created for your project. Primary Fix: Select the Poetry Interpreter
The most common and effective solution is to point VS Code directly to the virtual environment managed by Poetry.
Open the Command Palette: Press Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (macOS).
Select Interpreter: Type "Python: Select Interpreter" and select it.
Choose the Poetry Environment: Look for an entry labeled with Poetry or a path that matches your project name. If it isn't listed, you can find the path by running poetry env info --path in your terminal and choosing Enter interpreter path in VS Code to paste it. Configuration for Poetry You need to tell VS Code to use
To make this more seamless in the future, you can configure Poetry to create virtual environments inside your project folder.
In-Project Envs: Run poetry config virtualenvs.in-project true. This creates a .venv folder in your project root, which VS Code often detects automatically as a "Recommended" interpreter. Troubleshooting Persistent "Missing Imports"
If the correct interpreter is selected but the errors persist, try these steps:
Clear Pylance Cache: Open the Command Palette and run Python: Clear Pylance workspace cache. This forces a rescan of your environment.
Add Extra Paths: If you are using a non-standard project structure (like a src layout), you may need to add the source directory to Pylance's search path. In your .vscode/settings.json, add: "python.analysis.extraPaths": ["./src"] Use code with caution. Copied to clipboard Once selected, reload the window or restart Pylance
Restart the Language Server: Occasionally, Pylance gets "stuck." Running the Developer: Reload Window command from the palette often clears transient errors.
Disable the Warning: If the code runs perfectly and you simply want the "squiggles" gone, you can suppress the specific diagnostic in your settings:
"python.analysis.diagnosticSeverityOverrides": "reportMissingImports": "none" Use code with caution. Copied to clipboard
Here’s a concise review of the Pylance missing imports issue when using Poetry, including causes and solutions.
If your Poetry environment requires environment variables for Pylance to resolve imports (e.g., PYTHONPATH modifications), create a .env file in your project root:
PYTHONPATH=$workspaceFolder/src
VS Code's Python extension automatically loads .env files.
