I have a flask app that uses some enviroment variables, I don't now what has changed but now it doesn't read the variables in the .flaskenv file, already tried changing its name to .env, still not working.

This is the .flaskenv file:

    FLASK_APP=app
    FLASK_ENV=development
    CONSUMER_KEY=
    CONSUMER_SECRET=
    ACCESS_KEY=
    ACCESS_SECRET=
    SEC_USERNAME=
    SEC_PASSWORD=

In the app.py file:

    from flask import Flask, render_template, url_for, request, redirect, session, g
    import os

    s_user = os.environ.get('SEC_USERNAME')
    s_pass = os.environ.get('SEC_PASSWORD')

    print(s_user)
    print(s_pass)

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

It prints "none".

If i do flask run :

Usage: flask run [OPTIONS]

Error: Could not locate Flask application. You did not provide the FLASK_APP environment variable.

pip list:

As written in the flask docs:

If python-dotenv is installed, running the flask command will set environment variables defined in the files .env and .flaskenv. This can be used to avoid having to set FLASK_APP manually every time you open a new terminal, and to set configuration using environment variables similar to how some deployment services work.

make sure to run pip install python-dotenv

Edit

This flask seems to be very old, try updating it with

pip install -U flask
