When I did not install the module "flask", I ran into the problem you described:
The reason is that the module "flask" is not installed in the Python environment we currently use in VSCode.
Please use the shortcut key Ctrl+Shift+` to open a new VSCode terminal, it will automatically enter the currently selected environment, and then use the command "pip show flask" to check the installation location of the module "flask":
If it still shows that the module could not be resolved, it is recommended that you reinstall the module "flask".

May 26, 2021 -
Not sure if this is the right place for this question. I'm trying to use flask in visual studio code and went through the process of installing it. When I try to import it, I get a message saying "Import 'flask' could not be resolved from the source Pylance(reportMissingModuleSource)". How can I fix this?

Open a terminal in your project dir. Vscide should nothing to do with getting flask working. I don’t know how your env is configured though.
‘pip install pipenv’
‘pip shell’
‘pipenv install flask’
You should be good to go. Pipenv is my new lover 💙💙
Hope this helps

November 3, 2021 - In your project folder, create a folder for the app, such as hello_app, to separate its files from other project-level files like requirements.txt and the .vscode folder where VS Code stores settings and debug configuration files. Move the static and templates folders into hello_app, because these folders certainly contain app code. In the hello_app folder, create a file named views.py that contains the routings and the view functions: from flask import Flask from flask import render_template from datetime import datetime from .
