Troubleshooting Import Could Not Be Resolved in Python with Visual Studio Code
As a Python programmer, you may face issues when importing modules in Visual Studio Code (VSCode). One recurrent error is the import could not be resolved message, often reported by the Pylance extension. This guide will guide you through identifying and resolving these issues to streamline your development workflow.
Understanding the Issue
The import could not be resolved error typically occurs due to several reasons:
Virtual Environment: Your VSCode may not be using the correct Python interpreter.
Path Issues: Incorrect or relative module paths can cause import errors.
Pylance Configuration: Pylance settings might need adjustments to recognize the modules correctly.
Common Scenarios and Fixes
Let’s explore the common scenarios where this error may appear and the steps to resolve it.
Virtual Environment Not Activated
If VSCode isn’t using the right Python interpreter associated with your virtual environment, you’ll likely encounter import errors.
Solution:
Make sure you have a virtual environment set up: python -m venv env
Activate the virtual environment:
On Windows: .envScriptsactivate
On macOS and Linux: source env/bin/activate
In VSCode, select the correct interpreter via the Command Palette (Ctrl+Shift+P), then search for Python: Select Interpreter.
Incorrect or Relative Module Paths
Import errors may also arise if you use incorrect or relative paths for your modules.
Solution:
Ensure the module’s path is included in your PYTHONPATH. You can add this to your workspace settings in VSCode:

Testing with absolute paths can help identify if relative paths are causing issues.
Pylance Configuration
Pylance can sometimes fail to resolve imports due to its stricter type-checking and import resolution.
Solution:
Review your settings.json in VSCode and add or modify the following:

Specific Cases: Importing Requests
If you face issues with third-party libraries like requests:
Solution:
Confirm installation by running: pip show requests
If not installed, add requests to your project’s requirements.txt and install it: pip install -r requirements.txt
Ensure the correct interpreter is selected in VSCode, aligned with the environment where requests is installed.
Final Tips
Regularly update your VSCode and its extensions.
Use .env files to manage environment variables that can aid in module path resolution.
Review and adjust workspace settings to ensure all necessary paths are included.
By addressing these common pitfalls, you can resolve the import could not be resolved error and maintain a smoother Python development experience in VSCode.
Happy coding!
