Please do it like this.

bench --site site_name install-app hrms

Thank you sir. I run by “bench --site site_name install-app hrms”, but the same error.

Before installing hrms… make sure Bench is started… in another terminal window

bench start

And while the bench is running

bench --site site_name install-app hrms

You attempted to install the app on the site before now so you may have to remove the app first.

do the following
bench --site site_name uninstall-app hrms
bench remove-app hrms

if you still receive errors you can go to login to your site got to Module Def list and delete the app directly

How to do this specifically?

This error occurred with the system running in production mode.

Search for Module Def list
in the list find HR and delete it

Amazing! It can install like this operation only?
Thank you very much!

I got the same error. The solution is not working for me.
I guess if you replace the HR module from v13 to v14 there should be some workflow to make a smooth upgrade?
Are there any solutions available?

bench --site [sitename] mariadb

delete from tabModule Def where module_name = ‘HR’;

delete from tabModule Def where module_name = ‘Payroll’;
