Introduction

Python is a popular programming language that is widely used for web development, data analysis, and artificial intelligence. Flask is a popular web framework for Python that allows developers to build web applications quickly and easily. However, sometimes when working on a project, you may encounter an error that says "Import flask" is not recognized by Pylance. This article will guide you through troubleshooting this error.

Troubleshooting Steps

1. Check Flask Installation: The first step is to ensure that Flask is installed in your system. To install Flask, you can use the following command in your terminal:

pip install flask

If Flask is already installed, you will receive a message that says "Requirement already satisfied." If not, the installation will begin.

2. Check Python Environment: It is possible that you have multiple Python environments installed on your system, and Pylance is not configured to use the correct environment where Flask is installed. To check your Python environment, you can use the following command in your terminal:

which python

This will show you the location of the Python executable that is currently being used. Make sure that this is the same Python environment where Flask is installed.

3. Configure Pylance: If the above steps do not resolve the issue, you may need to configure Pylance to recognize Flask. To do this, you can add the following lines of code to your settings.json file:

"python.analysis.extraPaths": ["./path/to/your/flask/installation"]

Make sure to replace "./path/to/your/flask/installation" with the actual path where Flask is installed on your system.

4. Restart VS Code: After making changes to your settings.json file, you will need to restart Visual Studio Code for the changes to take effect.

Conclusion

In conclusion, encountering an "Import flask" error in Python while using Pylance can be frustrating, but there are several troubleshooting steps you can take to resolve the issue. By following the steps outlined in this article, you should be able to get Flask up and running with Pylance in no time.
