Facebook plugin not installed

Hi all,
I just updated all for newest version and then installed cordova-plugin-facebook4 . But if I want to use this plugin, console tell to me that:

Native: tried calling Facebook.browserInit, but the Facebook plugin is not installed. Install the Facebook plugin: 'ionic cordova plugin add cordova-plugin-facebook4'

I tried many times to reinstall platforms and node_modules. But no luck with this.

Is there something wrong?

EDIT:
Here is ionic info log:

Maybe you are using the plugin before platform.ready

Please move your code inside platform.ready()

I have the same issue. And yes, I use the plugin within the plaform.ready.
