@bkm I followed your steps from here (error-on-erpnext-ubuntu-18-04-lts-installation)
and I got this error. Any help?

About 10 days ago the install script and playbooks were fixed so that those temporary instructions were no longer needed. Sadly, it appears that a new set of issues have reared their ugly head and again it will take another pioneer to find a workaround set of instructions.

Although everything that goes into the forum makes sense at the time of it’s publishing, the pace and nature of erpnext/frappe changes frequently renders any workarounds useless in a very short period of time. Likewise, those instructions are likely no longer valid.

Additionally, after another very short period of time, any of yours or mine original posts lose their edit icon and cannot be revisited to be changed. This “feature” of the forum script creates a condition where expired or bad information (that was once good) cannot be edited by the originator and it is left there for others to stumble across later.

The post you sited falls into that same trap. I can no longer edit it.

Wiped system > installed Bench and Frappe (official documentation). But now I am stuck with another issue.
Installed Bench and Frappe successfully > new site “lok.local” but cannot install the “erpnext” app over it.
Downloaded it via "bench get-app erpnext GitHub - frappe/erpnext: Free and Open Source Enterprise Resource Planning (ERP) "
After cloning it, it runs the build command and that where it gets stuck.
The error:

INFO:bench.utils:bench build --app erpnext
yarn run v1.21.1
$ FRAPPE_ENV=production node rollup/build.js --app erpnext

Used these commands and fixed it

Step 1: bench setup socketio
Step 2: bench setup requirements

But I cannot run the command

bench setup production
#output
WARN: superuser privileges required for this command

when I run the command with sudo

sudo bench setup production
#output
sudo: bench: command not found

sudo pip install -e bench-repo

Running this command solved it.
