Problem with running npm start - listening to default 8081 port

[erinjerri]

These threads helped me identify the problem:
#12

figuring out I needed to take steps in iOS app delegate:
#240

First I had to make sure I added the main.jsbundle to the project (the reference in the thread )

figuring out it was the 8081 port officiallyL
https://github.com/facebook/react-native/blob/master/packager/packager.js#L35

But I still kept getting the same problem and @mbrgm helped me through it.

After that I tried
sudo lsof -nP -iTCP:8081 -sTCP:LISTEN

So I wrote in $PID, typed in my admin password:

We located that on node this was the issue '3960'

kill 3960 and the sudo command above.
then I finally got the packager to run.

note that your kill $pid command didn't actually kill anything, you need to run pkill 3960. But before that, try ps aux | grep 3960 to see full path to the process that is taking that port.

Yup, I did that this morning too. Still not working unfortunately.

Finally got it to work, plus the curl thing I couldn't do. I had to recomment out things and do a fresh restart since I think OSX was locking up everything.

@frantic Should I send a PR adding a hint about the EADDRINUSE error to the troubleshooting section of the docs?

[frantic]

@mbrgm - as of #736 we provide better error message. Also the troubleshooting page already has instructions how to find out which process is taking the port and what to do. Or am I missing something?

[mbrgm]

@frantic Sorry, I missed that. This project is progressing so fast, I should've looked there before ;)
