cannot install any plugins . failed with check the permissions

[jaheshkhan]

today i tried to install fresh install of netbox. so now the netbox version is 2.11.6

python version is 3.8.5

Then i tried to install plugins like

1. nextbox-ui-plugin,
2. ntc-netbox-plugin-onboarding ,
3. netbox-topology-views.

none of the above plugin installed all ended withe permission issue as below

"ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: '/opt/netbox/venv/lib/python3.8/site-packages/nextbox_ui_plugin'
Check the permissions."

I didnt understand what permission im missing

The steps followed are as follows:
$ source /opt/netbox/venv/bin/activate
(venv) $ pip3 install nextbox-ui-plugin

/opt/netbox is owned by root:root, which means you won't have write access to it as a standard user.

Try this instead:

sudo -i
source /opt/netbox/venv/bin/activate
pip3 install nextbox-ui-plugin

Then add your additional packages to /opt/netbox/local_requirements.txt so that they're reinstalled when you next upgrade NetBox.
