Error "from migrate.versioning import api". How to overcome?

Question

Flask

Hello!
Decided to try the Flask tutorial. More precisely, its translation: habrahabr.ru/post/196810
In this part, the author gives the db_create.py script, in which I get an error

All components were installed according to the tutorial in virtualenv. Versions that were indicated there.

What could be the cause of the error, and how to overcome it?

Thank you very much for your help!

Answer 1

Reinstalling everything helped. Took this as a solution :)

Answer 2

The required package is in the sqlalchemy-migrate library. Most likely, launching would help you
. Perhaps you accidentally missed this line.
