this._nativeModule.addListener is not a function.(In 'this._nativeModule.addListener(eventType)',

'this._nativeModule.addListener' is undefined)

@rosegun38 Maybe you should upgrade your react-native-cli.. try npm install react-native-cli -g

anything new here?

[MillerDix]

$ sudo lsof -n -i4TCP:8081 | grep LISTEN
$ kill -9 < node id >
This should work..

Any help would be appreciated

@n8stowell82 : this link is broken

[n8stowell82]

that is strange, seems like the "link" markdown was breaking the URL. Anyway here is the link to the issue, and my comment is the last one. I also updated the broken link to work properly. Hope this helps
