I mean post text as text, not screenshots. Images are unsearchable, unselectable for copy/paste, decay, are unreadable by screen readers, are unreliable, and in your particular case you are using some janky image host that my uMatrix plugin refuses to load.
I believe something else in your project (not @ionic-native/clipboard) is requiring typescript 2.0.9. Do you have that version explicitly declared in your package.json? If so, try changing it to 2.2.1 and running npm install. I just added @ionic-native/clipboard to a v3beta version of the conference app (which is using TS 2.2.1) and did not get your error, so I believe there is a different cause.
