I have the latest PyCharm CE and am using it with
pip freeze > requirements.txt
from flask.ext.login import current_user, login_user, logout_user, login_required
current_user, login_user, logout_user, login_required
The problem may lay in PyCharm picking up faulty 'Interpreter Paths' for your virtual environment. Go here:
PyCharm (menu) -> Preferences (Menu option) -> Project: <name> (Dropdown) -> Project Interpreter (Menu option) -> 'Settings' button (Looks like a gear) -> More (Menu option) -> Select your virtualenv interpreter -> Click 'Show paths for interpreter' button (on bottom of list window)
Now that you're in this (admittedly tortuously found) location, you should see paths being used by this interpreter. If my theory is correct, these are pointing to global system locations. To add the virtual environment paths, you should click the
+ button and add corresponding paths that exist inside your virtual environment. Once you're done with this, it's a good idea to select the global system paths and click
- to remove them. Click apply, and go to
File -> Invalidate caches / Restart to reload PyCharm.
This should get your interpreter to be pointed to the correct location for the libraries you've installed into your virtualenv, and you should no longer be getting the import error. Note that even with this fix you will not see your libraries under the
Project Interpreter, but they should be being loaded.
