@Varun-Ganesh-D

@administrators PLZ HELP ME OUT

[julian]

Run ./nodebb build and restart your NodeBB.

[Varun Ganesh D]

@julian is that command required to run for every plugin install?

[Varun Ganesh D]

@julian Followed this. But not worked.
All plugins same problem.

Also i run ./nodebb plugins
It showed below output.
I installed and activated google analytics and Facebook SSO
But in console it showing not installed

[julian]

If ./nodebb plugins does not show it as installed, then it is not installed (or cannot be found in node_modules/ directory. Make sure you install it either from the ACP or via npm/yarn npm i nodebb-plugin-whatever

[Varun Ganesh D]

@julian OK. So i have to install all plugins through terminal?? I've installed and activated from Dashboard.
Sometimes plugins installed from dashboard automatically deletes.

[PitaJ]

Because of how heroku works, you must install your plugins before deploying your site. You can do that through the ACP on your local machine of you wish, or with npm.

[Varun Ganesh D]

@PitaJ Yes. I got it now.. but when i update system all plugins installed are gone automatically. is there any command to add to package.json file? already installed plugins. but need to add without changing current production

[julian]

You'll need to add it to package.json on your local machine, and then git commit it into Heroku... or something -- I don't really recall how Heroku works, but it's something like that.
