Import error: No module named 'secrets' - python manage.py not working after pull to Digital Ocean

Question

I'm following along a course - Django development to deployment.
After pulling it to Digital Ocean everything else ran smoothly. Until
I tried running python manage.py help

(env) djangoadmin@ubuntu-1:~/pyapps/btre_project_4$ python manage.py help

and I get this error.

Traceback (most recent call last):

ImportError: No module named 'secrets'

I'm a newbie and have been stuck on this for a while. I just want to know what could possibly cause this.

Answer 1

The secrets module was added to Python in version 3.6. Your host is using Python 3.5, hence the secrets module is unavailable. You need a host with Python 3.6+, or a version of Django that doesn't depend on the secrets module

Answer 2

Had the same issue, solved it by specifying the python version I have installed. i.e

$ python3
>>> import secrets
>>> secrets.token_hex(16)
