python - virtualenv: "cannot import name 'Flask'" -
this question has answer here:
maybe i'm doing wrong, after 1 hour of staring @ code i'm not getting smarter.
my problem virtualenv. set venv2 , venv3 folders in home-directory. installed flask on both of them, alongside other packages.
the problem can't run helloworld-example flask.
from flask import flask app = flask(__name__) @app.route('/') def hello_world(): return 'hello world' example venv2:

i don't see file structure, can't sure, if have file called flask.py in same folder, python import instead of flask module
