Impossible to start the app

Hi there !
I’m trying to install ERPNext on my VPS since few hours. I follow the setup instructions (Git Readme), i can’t start the app (last step) with command

bench start

I have a lot of warning but no erros. I don’t understand the issue…
VPS is under debian 9 and run caddy. I try to stop caddy but still the same issue.

This is the command output :

enzo@VDenis:~/ERPNext/frappe-bench$ bench start

Thank’s for you help :slight_smile:

If you’re trying to setup erpnext for production (usage in a company) you want to have it in production mode. One of the things this does is automatically start your services. Only developers need bench start.

https://github.com/frappe/bench shows that to setup production simply do

bench setup production

You installed ERPNext in development mode.
Try this

sudo service supervisor stop
sudo service nginx stop
bench update --reset
bench start

Your supervisor process has terminated/stopped. To restart it, try this

sudo supervisorctl restart all

but this is probably just a symptom and not the actual issue. The most common cause of this problem is a memory setting mismatch which is often fixable via this command (although I personally don’t like to set it so high as it can waste RAM)…

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Hi,
Thank’s for your answers. I decided to re install as production.
It’s work better but a new issue appear when i try to execute python script :

Failed to fetch https://deb.nodesource.com/node_8.x/dists/stretch/main/source/Sources  The HTTP server sent an i                                                     nvalid reply header\nE: Some index files failed to download.

I don’t find other same issue here…
Thank’s
