Import "flask" could not be resolved from source Pylance (reportMissingModuleSource)

Question

When I am writing

from flask import Flask

One Yellow line is coming up under flask and stating Import "flask" could not be resolved from source Pylance (reportMissingModuleSource) . Also, I am able to do the work with this package also successfully. But the thing is, I am not able to use autosuggesstions for Classes and methods very well.

Further:

1. I have checked that flask is installed successfully.
2. Also I visited this thread https://github.com/microsoft/pylance-release/issues/236

And I set up my settings.json in vscode as follows:

"python.analysis.extraPaths": [
    "/media/sarimurrab/New Volume/COURSES/Flask/FlaskMigrateforDatabaseMigrations/2"
]

But Still, unable to resolve the error.

Answer 1

When I did not install the module "flask" in the Python environment currently used in VSCode:

Please use the command "pip --version" to check the source of the module installation tool "pip", the module is installed at this location:

Then, we can use the command "pip show flask" to check the installation location of the module "flask": (It checks whether the installation location of the module is consistent with the Python environment displayed in the lower left corner of VSCode.)

If the "reportMissingModuleSource" message is still displayed here, please reload VS Code.

Answer 2

Are you using a Virtualenv? If so make sure that VSCode is using the virtualenv as your python interpreter, otherwise it will not be able to pick up the packages that you installed inside this virtualenv.

To do so, click on the Python interpreter in your bottom bar, you should get a list of possible python interpreters including your virtualenv.
