A search on this error above points to this Error on install ERPNext to new bench instance

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.

bench setup requirement…

outcomes are :point_down::point_down::point_down::point_down

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'

Hi Sir,

I followed above steps now got below error

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

Filesystem Size Used Avail Use% Mounted on
udev 481M 0 481M 0% /dev
tmpfs 99M 760K 98M 1% /run

tmpfs 99M 0 99M 0% /run/user/1000

It looks like memory is unable to reallocate again…

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

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.

lol absolutely yes

reboot can fix your problem

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