Error: not a valid NativeScript plugin

[darko-bw]

When I am trying to install a plugin it gives me an error:

@nativescript-community/texttospeech is not a valid NativeScript plugin. Verify that the plugin package.json file contains a nativescript key and try again.

I am using latest NS:
Component nativescript has 8.0.2 version and is up to date.
Component @nativescript/core has 8.0.8 version and is up to date

I experience the same issue, doesn't seem with the plugin itself but rather an ENV issue
I installed it using npm and continued working fine ..
npm i --save nativescript-texttospeech
