ImportError: Module import failed for Invoice Discounting

Install / Update Setup
1

Almost finished manual install on DO Droplet. Trying to install ERPNext on erp.mywebsite.com using bench.

Bench version: 5.8.1
ErpNext version: 13.3.0

Are these versions compatible?

Running [ bench --site erp.mywebsite.com install-app erpnext ] gives the below error:

I was using frappe version 14.x.x.x.
Replaced it with frappe version 13 and now it is working fine.

Now figuring out how to get rid of these warnings -
Browserslist: caniuse-lite is outdated.
Error: ENOSPC: System limit for number of file watchers reached

Thanks. I ended up rebuilding the droplet because i installed it in ‘editable mode’ by mistake.
Same issue as this one -

This week I tried three methods of installing (easy install script, docker installation and manual)

Easy install is not maintained and gives a lot of errors. Failed to install.

Docker seems good if you are on low budget system. But documentation can be improved for non-linux users. Was able to install it but not use it (difficult to understand Traefik routing. I am sure this can be solved easily)

Manual install using @bkm 's method. By far the best documented step by step installation with explanation i could find on the internet.

Now figuring out how to use ERPNext.
