How to solve unresolved import in VSCode?

Question

I am trying to learn Flask, I use Ubuntu 19.04 and I am writing code in VSCode. After following the attached tutorial, I keep having the problem: unresolved import"flask_mysqldb" and the same with wtforms and passlib.

I have installed all requirements, and just to check, I try to install again and I receive the message:'Requirement already satisfied: mysqlclient in "someplace"/.local/lib/python2.7/site-packages

I thought that maybe I am using python 3.7 but it installs itself in 2.7? But it never asked me where to install.

This is the video tutorial I am following: https://www.youtube.com/watch?v=addnlzdSQs4

from flask import Flask, render_template, flash, redirect, url_for, session, loggin
from data import Articles
from flask_mysqldb import MySQL
from wtforms import Form, StringField, TextAreaField, PasswordField, validators
from passlib.hash import sha256_crypt

the first two imports work just fine, the others are underlined with green and receive error messages.

ex:

unresolved import 'flask_mysqldb'

unresolved import 'wtforms'

unresolved import 'passlib.hash'

Have you tried to set the interpreter in VSCode to correct value (including your virtualenv if you have one)?

Open the command palette (Ctrl-Shift-P) and choose "Python: Select Interpreter".

For more details, see: https://code.visualstudio.com/docs/python/environments

I find that when installing a new package this tends to happen, so I restart vs-code after checking my interpreter. – Jean Marie Jun 05 '20 at 13:29

I have had this problem several times and it often works with just "exiting" VSCode since VSCode sometimes doesnt check the path. It uses the "old" settings or "path". By exiting the program and restarting it it updates this and it works (if its this problem)

Just use `Ctrl+Shift+P`, type "reload" and select Developer: Reload Window instead. – Robert Mar 11 '22 at 10:37

I stumbled across this issue while using VSCode with python3 venv.

Premise: While @truth answer pointed me in the right direction, I still could not select the correct interpreter: the right one for me would have been the one created in my venv folder but it wasn't shown on the venv options and even if I browsed to the right folder via the GUI it won't allow me to choose it (because it is a symlink perhaps?)

TLDR: For mac users like me that have python2 installed by default, python3 installed via brew and are using a virtual environment (spawned with python3 -m venv), the solution is the following:

save all your work and close VSCode completely ( command+Q )
open your terminal and navigate to your project folder. Ensure that your virtualenv is activated
open the project from the root folder with: code .
open the command palette ( command-Shift-p ) and type "Python select interpreter" and press enter
select the interpreter from the list that reference your venv folder

Done, your dependencies should now resolve.

After trying many things and not working ,ended up restarting everything. Erased all the files and did it again. Somehow it worked. Must have been some mistake while setting up.

Probably, You used command pip install flask-wtf, but it's wrong way. First You have to use command : sudo apt install python3-pip, and next install flask-wtf with command : pip3 install flask-wtf, because you need libraries for python3, not for python2.
