Error ImportError: uWSGI is not available, how to fix?

Question

Django

I have a destributor.csv file that needs to be unloaded into the database model.
There is a script called import_csv.py
I run it with the following command from the script directory:
../../../manage.py import_csv "/home/webuser/fcprj/media/destributor.csv"
an error is displayed:

I found some answers, but still something does not reach how to fix this error

As I understand it, I need to register something in the virtual environment, but I can’t figure out what and where.
The problem occurs in this line:
emp.save()

Judging by the trace, it crashes when saving, at the same time, it tries to send an error message to the mail, and then it crashes further due to the lack of uwsgi, which you can install pip install uwsgi or fix sending mail in settings, and then see what it is crashes on save.
