How to fix pymongo import error?

Question

Flask

Hello,
when importing a module, pymongo gives an error:
File "..../python2.7/site-packages/flask_pymongo/__init__.py", line 37, in
from pymongo.read_preferences import ReadPreference
ImportError: No module named read_preferences

What is the module And what package does it come with?

Answer 1

Everything was decided, he simply imported the module from the main directory where pymongo was not spawned, and not from one of the virtual environments as it should have been, everything was decided by editing the paths to the desired package repository.
