How do you get the linter working for ros2 libraries in visual studio code for a source ros2 installation?

edit

I'm trying to figure out how to get auto-complete working in vs-code for my source installation of ros2 but position of directories and overall folder structure seems to be different on the source installation from the apt-get install.

E.G:

rlcpy is in /opt/ros/foxy/lib/python3.8/site-packages on the apt-get install method but rlcpy seems to be in (directory you installed it in /ros2_foxy/src/ros2 on the source installation.

launching packages through "ros2 launch <package-name> <package-name-launchfile> works, but when I want to work on a program for my pi nodes in the IDE, the linter fails to import the ros2 libraries because it can't find them, I'm using the settings.json file of:

{
    "python.autoComplete.extraPaths": [
        "/opt/ros/foxy/lib/python3.8/site-packages",
        "~/ros2_foxy/src"
    ],

}

but this does not work.

I've done both source ~/ros2_foxy/install/setup.sh and (directory of ros2 package) source install/setup.sh, but neither of these fixes imports not showing in the linter.

This is the code im trying to run:

#!/usr/bin/env python
import time
import serial
import rclpy
from rclpy.node import Node

from std_msgs.msg import String


class MinimalSubscriber(Node):

    def __init__(self):
        super().__init__('minimal_subscriber')
        self.subscription = self.create_subscription(
            String,
            'topic',
            self.listener_callback,
            10)
        self.subscription  # prevent unused variable warning

    def listener_callback(self, msg):
        self.get_logger().info('I heard: "%s"' % msg.data)


def main(args=None):
    rclpy.init(args=args)

    minimal_subscriber = MinimalSubscriber()

    rclpy.spin(minimal_subscriber)

    # Destroy the node explicitly
    # (optional - otherwise it will be done automatically
    # when the garbage collector destroys the node object)
    minimal_subscriber.destroy_node()
    rclpy.shutdown()


if __name__ == '__main__':
    main()

Error im getting:

Unable to import 'rclpy.node'

how do i get the vscode workstation working so the linter works?
