Flask ImportError: No Module Named Flask

If you are getting the error message “ImportError: No Module Named Flask” when trying to run a Flask application, it means that Flask is not installed in your Python environment. Flask is a popular web framework for building web applications in Python.

To resolve this issue, you need to install Flask in your Python environment. You can do this using pip, the Python package manager. Open your command line or terminal and run the following command:

pip install Flask

This command will download and install Flask and its dependencies in your Python environment. Once the installation is complete, you should be able to run your Flask application without encountering the ImportError.

If you continue to encounter the ImportError, you may need to check your Python environment and make sure that it is properly configured. You can also try uninstalling and re-install Flask to see if that resolves the issue.

It’s important to have Flask installed in your Python environment in order to build and run web applications using the Flask framework. Make sure to keep your Flask installation up to date to avoid any compatibility issues with other packages or modules in your Python environment.
