Trying to import flask but I get the error:
ImportError: No module named Flask
after:
import Flask
I just installed it using terminal (Mac OS X):
JoeDangers-MacBookPro:~ joedanger$ $sudo easy_install Flask
Searching for Flask
Best match: Flask 0.10.1
Processing Flask-0.10.1-py2.7.egg
Flask 0.10.1 is already the active version in easy-install.pth
Any thoughts as to why this is not working?
The module is called flask:
from flask import Flask
PYTHONPATH is invalid or the package didn't install correctly. Make sure easy_install uses the same PYTHONPATH as your Python interpreter.$ pip install virtualenv
Create virtualenv:
$ virtualenv venv
Activate virtual environment:
$ source venv/bin/activate
Make sure your terminal like this:
(venv) user@username:
Installing flask
pip install flask
And you can import flask without error :)
To deactivate, just type:
deactivate
uninstall the package and then reinstall it again using pip " pip install Flask " after that use this command to import the package:
from flask import Flask
edit:
are you using virtualenv ? if not then i recommend you to install it first
use this command:
pip install python-virtualenv
If your using mac terminal then check the python version which is linked to pip. Suppose for example if pip is linked to python version 2.7 use
➜ ~ python
Type "help", "copyright", "credits" or "license" for more information.
>>> import flask
(or)
➜ ~ python app.py
else if python version is 3.0 and above
➜ ~ python3
Type "help", "copyright", "credits" or "license" for more information.
>>> import flask
(or)
➜ ~ python3 app.py
By using these commands you can check is flask is installed and if so for which python version
