Fresh react-native ios app not building?

Question

Below is the details about my environment and logs of the build failure. Anyone facing similar issue or know steps to overcome this please do point me out to relevant steps or docs.

• Xcode: 7.2.1
• Node: v5.9.0
• npm: 3.7.3
• react-native-cli: 0.1.10
• react-native: 0.22.2

Running "sudo react-native run-ios" leaves me with the below logs.

LOGS:

Answer 1

do not run:

sudo react-native run-ios

you should run:

react-native run-ios

your root account does not have Simulator configured properly to run the iOS so you see "No devices are booted" error in your log!

Answer 2

I have similar issue on OS X El Capitan v10.11.4

node --version v6.0.0
npm --v 3.8.8
react-native-cli: 0.2.0
react-native: 0.24.1
watchman --v 4.4.0
xcode 7.3

I have created an issue on react-native github.

I was able to resolve my issue:

For me port 8081 was in use :

lsof -n -i4TCP:8081

node 7601 arun 23u IPv6 0xc6b249599e5f1169 0t0 TCP *:sunproxyadmin (LISTEN)

So I followed the instructions from React Native Troubleshooting and killed the pid

kill -9 7601

and ran the command react-native run-ios again and everything worked as expected (on node 6 as well).
