A search on this error above points to this Error on install ERPNext to new bench instance - #3 by Taher_Khalil

So try this - from frappe-bench run

bench setup requirements

Hi ,

when I run bench setup requirement , it got stuck on some .js file ( list.min.js)…

unable to proceed further.

for moving next step I have to first reboot my AWS instance …

How to solve this.

Re your post # 3 -

I can’t say I follow what you are telling me.

Please you may want to include session output to help folks recognize context.

This may help you with clues Cannot find module 'rollup'

packet_write_wait: Connection to 3.16.124.136 port 22: Broken pipe

Previously, I got same error packet_write_wait: Connection to 3.16.124.136 port 22: Broken pipe , that time team suggested to increase different packet size in my.conf , after that it was working for some time. ( which stopped working after ver 11 to 12 update , after re installation whole set of new problem started hence this case got opened)

Now following your latest solutions facing same packet write wait issue.

Another issue what I am observing here memory allocation

System have space 8G. after install ERP Next automatically around 5G allocate to below process. When I check my system disk space using df -h it show only near 2G is free. In version 11 when it was working I observed free memory was around 6G

root@ip-172-31-46-206:~# df -h

udev 481M 0 481M 0% /dev

It looks like memory is unable to reallocate again…

9

A broken pipe means you have network issues so you best check with your Internet Service Provider

10

You are confusing memory with disk storage space!?

For a test system 2 Gbytes ram memory and 20 Gbytes disk space is probably the basic minimum.

11

lol absolutely yes

12

reboot can fix your problem

Hello Thanks in advance i am facing below issue after restoring backup:

Run this commands it solved my issue

sudo supervisorctl stop all
This command stops all processes managed by Supervisor

sudo service nginx stop
o to stop the Nginx web server. service is a command used to run System V init scripts, and in this case, it’s stopping the Nginx service

and then do
bench start
