Open your browser to http://localhost:8081/vr/index.html.

in terminal it shows

`$ npm start

I've been unable to repro your problem, my test machine was on a mac.

Can you provide more details, version of npm, yarn, dev machine, etc as without this information we will be guessing.

Hi Mike,

I found problem, the port number 8081 is being used by mcAfee Antivirus. i have made changes in node node_modules/react-native/local-cli/server/server.js default port no to 8087

now its working.

Thanks

good resolve

another solution i found: insted of npm start we can run command

npm start --port 8087

(in this case no need to change any module files.)
