12,131 PointsCan't import Flask
Any idea why does this throw an "importError: cannot import name: 'Flask'?
from flask import Flask
from flask import render_template
app = Flask(__name__)
app.run(debug = True)

25,493 PointsOk I figured it out. You can’t call the file flask.py because then its trying to import the name Flask from itself. Try naming the file app.py or something other than flask and it will work. You have to be careful in naming your files so that they don’t conflict with other packages.

25,493 PointsYou have to install flask :) Try running pip install flask in your terminal. If that doesn’t work, try sudo pip install flask

12,131 PointsI'm using the workspaces, isn't flask installed already?

25,493 PointsI would think so... did that work?

You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
pyenv: cannot rehash: /usr/local/pyenv/shims isn't writable
and when I try to run the file I get the same error:
treehouse:~/workspace$ python flask.py
Traceback (most recent call last):
File "flask.py", line 1, in <module>
from flask import Flask
File "/home/treehouse/workspace/flask.py", line 1, in <module>

ImportError: cannot import name 'Flask'

25,493 PointsSee the answer, you need to run
sudo pip install flask

12,131 PointsNot working either...
treehouse:~/workspace$ sudo pip install flask
bash: sudo: command not found

25,493 PointsThat’s strange… can you send me a snapshot of the workspace?
Elias Sersun Uhalde
12,131 PointsOookey, i'm an idiot. Thank you so much for your help!

25,493 PointsBy the way, you don’t have any routes, I’m not sure if that was what you’d wanted
