[Close] Uncaught ReferenceError: Tracker is not defined

Hay all, I’m new here. I’m trying to write small code with meteor 1.8.0.1 and react 16.5.0, when I added some code, in my browser console show up the error

Uncaught ReferenceError: Tracker is not defined
    at setup (<anonymous>:1145:6)
    at <anonymous>:95:31
    at <anonymous>:103:12

I’ve been try but there’s no way out, any solutions or just info?

You need to add the tracker package manually. Somehow this is not documented and in most cases the package is still needed.

meteor add tracker

Thanks man, sorry for late reply, actually, the error syntax came from react developer tools extension in chrome. I already remove that and the error not show up again.
