Console for this task does not seem to be working. Keep getting an import error for flask.

Whilst doing the flask video I am unable to run my program due to an import error. Now this did work yesterday however it is not working today, could somebody from the Treehouse team please advise?

treehouse:~/workspace$ python app.py
Traceback (most recent call last):
File "app.py", line 2, in <module>
from flask import (flask, render_template, redirect,
ImportError: No module named flask

Kind Regards

Taylor, it seems the PATH environment is not correct on Workspaces. python is pointing at python2 not python3.

The short-term workaround is to use python3 app.py

Simple enough I think, try this.

from flask import Flask, redirect, render_template

Hi Josh tried changing the Flask from lower case to upper case and it has not made a difference. Thanks for your prompt help though.

Taylor, are you saying you are still getting the exact same error "ImportError: No module named flask" (note lowercase f) after you change your import statement to use upper-cased Flask?

Right. It's complaining about the from flask module missing not the import f/Flask attribute. If it were due to import f/Flask you would have seen a different error:

ImportError: cannot import name....

Not sure if the full code will help in this circumstance as it seems to be a direct Flask import problem. I think your right they maybe doing some sort of upgrade , or have some of outage.

Again thanks for taking the time to look into and answer my question.

Enjoy your evening.
