Issues getting Flask-PyMongo and Flask-Cors to work in my venv-CodePudding

I just started the app with the following code:

 from flask import Flask, request, jsonify
 from flask_pymongo import PyMongo, ObjectId
 from flask_cors import CORS

app = Flask(__name__)
app.config["MONGO_URI"]="mongodb://localhost/crudapp"
mongo = PyMongo(app)

CORS(app)

db = mongo.db.users

if __name__ == "__main__":
    app.run(debug = True)

In my explorer I have something like:

>Project Folder
  >Backend
    >src
      app.py
    >venv

I'm getting the same error for these two lines:

from flask_pymongo import PyMongo, ObjectID
from flask_cors import CORS

It says 'Import "flask_pymongo" could not be resolved' and 'Import "flask_cors" could not be resolved from source.' I tried reinstalling it within the venv and globally, nothing worked. I did some digging and found a post on reddit where someone said they solved this by pressing Shift Command P, finding the interpreter for Python and changing it to one following the path of the virtual environment. I tried that, and found two alternative interpreters to use, neither of them worked. I'm out of ideas.

EDIT: If it matters, the file path for the site-packages is:

Project Folder > Backend > venv > lib > python 3.9 > site-packages

Any help would be greatly appreciated!

CodePudding user response：

I got it by restarting the project from scratch and following a tutorial for setting up a virtual environment in mac (the tutorial I was originally watching was on windows, not sure if that made a difference). Anyway, heres what I did. In terminal first:

python3 -m venv venv

then:

source venv/bin/activate

then:

pip install Flask Flask-PyMongo Flask-Cors

Finally, I typed Shift Command P select interpreter and ./venv/bin/python

It works! I hope this can help someone else one day.
