6 years ago Hey @aiiins thanks a lot for taking time to report the issue.
I tried the steps on 3.6.1, and was not able to reproduce the issue.
My guess is your flask command is to pointing to a different script from a previous installation of flask that was probably done without creating a virtual environment. So when you run flask run, it is still points to the previous one. Try this
$ which flaskFor the flask run command to work it should point to the flask script inside the venv/bin/ folder, where venv is the directory created once you did python -m venv venv.
For example, in my machine
(venv) t (7) flask_team_project $ which flask
/Users/t/CodingWorkshops/problems/webdev/flask_team_project/venv/bin/flaskTry running this instead, and see if you are getting expected result
(venv) t (7) venv/bin/flask run
Here's the error I get when running
flask runafter installing all the requirements and setting up a venv.`(venv)

After this, I tried omitting all references to
