ImportError: No module named flaskext.sqlalchemy

I am trying to use the Sign in with SteamID snippet from the Flask site. However, I get

ImportError: No module named flaskext.sqlalchemy
when I try to run it, and PyCharm says
Uresolved reference "flaskext"
and
Uresolved reference "OpenID"
. I re-installed Flask-OpenID and Flask-SQLAlchemy to make sure they were there. Why am I getting this error and how do I fix it?

Answer Source

That snippet is really old. flaskext is no more (or at least very deprecated). Refer to packages directly rather than through flaskext or flask.ext.

from flask_sqlalchemy import SQLAlchemy

Flask-SQLAlchemy (and most other extensions) no longer register in the flaskext namespace, and flask.ext is deprecated. The only correct way to refer to extensions now is by directly importing them.

If you're still getting an import error, then you didn't install the package in the same Python environment you're running. Make sure you're using a virtualenv.
