There’s no install-app, use etc here.

frappe@testserver:~/frappe-bench$ bench install-app app_name
Usage: bench [OPTIONS] COMMAND [ARGS]...

Error: No such command "install-app".

What’s going wrong here?

Activate the bundled virtual env. It should be found at apps/env

3

@tundebabzy did. Still the same. And I think you mean frappe-bench/env

4

What do you mean by Bundled Envirnment ? Can you through some light on it ?

@mr-karan login with the sudo user used to install ERPNext. then
cd /home/“sudoUser”/frappe-bench/
source env/bin/activate

then you can run all bench commands. Do not change the directory
to get out of the environment. simply type
deactivate
