I'm having the same issue. Upgraded from 0.16.1 to 0.16.3 and inventree no longer starts up. Tried downgrading back to 0.16.1 but that didn't fix it.
I should really start taking snapshots before these upgrades :(

[StormTrooper]

I found the issue - looks like all the language files are missing.
For example under
opt/inventree/env/lib/python3.9/site-packages/rest_framework/locale/en_US/LC_MESSAGES
The folder is empty, this is the same for every language.

I checked on a older backup I had and the django.mo file is missing. I copied this file for just the en_US language and I'm now able to start inventree up and it's again working. (Other languages are all still broken)

Old test server:

root@inventree-server:/opt/inventree/env/lib/python3.9/site-packages/rest_framework/locale# find -name django.mo | wc -l
59

root@inventree-server:/opt/inventree/env/lib/python3.9/site-packages/rest_framework/locale/en_US/LC_MESSAGES# ls -la
total 12
drwxrwxr-x 2 inventree inventree 4096 Sep 22 11:11 .
drwxrwxr-x 3 inventree inventree 4096 May 20 11:33 ..
-rw-rw-r-- 1 inventree inventree  337 Sep 22 11:11 django.mo

Upgraded to 0.16.3 (With my fix):

root@inventree-server:/opt/inventree/env/lib/python3.9/site-packages/rest_framework/locale# find -name django.mo | wc -l
1

0.16.3 Prior to my fix:

root@inventree-server:/opt/inventree/env/lib/python3.9/site-packages/rest_framework/locale/en_US/LC_MESSAGES# ls -la
total 8

• What prompted you to look at the rest_framework library directory?
• Is it just for the rest_framework library that translation files are missing?
• Are the InvenTree files missing too?

[StormTrooper]

It was more by luck. I know nothing about rest_framework but saw the error was about python language files missing so started search for folders that stored the locales and came across the missing files.

I've checked and don't see any other locales missing from other subdirectories.
Also don't see any other files missing.

@matmair @wolflu05 this has now come up twice. No idea what might be going on here.. Any thoughts?

[matmair]

No idea, the shipped stuff has not really changed. On the road without my normal dev setup right now so hard to debug

[ShafiqSadat]

Same!
