Installation missing Python dependencies

[siege801]

Hi Everyone,

I'm trying to get NetBox up and running on a Ubuntu 20.04 LTS Server. I have followed the documentation found here on readthedocks.io. When I get to the stage of launching the development server, I'm running into trouble.

python3 manage.py runserver 0.0.0.0:8000 --insecure

Returned:

Traceback (most recent call last):
  File "/opt/netbox/netbox/manage.py", line 8, in <module>
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'

So I ran:

sudo pip install django-filter

The same situation repeated:

ModuleNoptFoundError: No module named 'psycopg2'

So I ran sudo pip install psycopg2
Which gave ModuleNoptFoundError: No module named 'corsheader'

So I ran sudo pip install django-cors-headers
Which gave ModuleNoptFoundError: No module named 'debug_toolbar'

This continued with the next four modules:

sudo pip install django-debug-toolbar
sudo pip install django-graphiql-debug-toolbar
sudo pip install django-tables2
sudo pip install django-prometheus

Which eventually landed me at:

ImportError: cannot import name 'force_text' from 'django.utils.encoding' (/usr/local/lib/python3.9/dist-packages/django/utils/encoding.py)

I had confirmed that the requirements.txt line had been run from within the update.sh. I even re-ran it with php install -r requirements.txt, but I'm still stuck at the same point.

Can any one provide some guidance on what might be going wrong?

Notably - at the end of the upgrade.sh script, there is an instruction to restart netbox and netbox-rq via systemctl, however there are no systemd units found.

I have checked and triple checked to ensure I didn't skip any steps - even repeating through the steps to no avail.

Looking forward to your advice.

No no no... don't go installing random packages into your global system, you'll just create a mess.

Python installs all its packages into a virtualenv, and you have to "activate" it in your shell before you can run any Netbox utilities:

cd /opt/netbox
source venv/bin/activate
python3 manage.py runserver 0.0.0.0:8000 --insecure

(you can use a single dot . instead of source)

It is documented here as part of the "Create Superuser" step. However this isn't persistent, it just affects the current shell, so whenever you open a new shell you have to activate the environment within that shell.

at the end of the upgrade.sh script, there is an instruction to restart netbox and netbox-rq via systemctl, however there are no systemd units found.

That's because you haven't finished following the installation instructions. That part is here.

I'm also experiencing issues with the Netbox installation. I belief a django installation step was missing configuration steps.

Is there a way of determining from a working Netbox deployment ?

Performed the Netbox installation again. This is the console dialog when attempting to run the

(venv) root@Netbox:/opt/netbox/netbox# python3 manage.py runserver 0.0.0.0:8000 --insecure
Performing system checks...

Appreciate any guidance.

I was able to figure this out after watching the instillation video. The Netbox writeup is missing the following:

After the following command is entered:

python3 ../generate_secret_key.py

The Key needs to be copied to the configuration.py in the previous step
