Here\'s my environment:
➜ AwesomeProject node --version
v6.3.0
➜ AwesomeProject npm --version
3.10.3
➜ AwesomeProject react-native --version
react-native-cli: 1.0.
I have just solved the same question.
First try using react-native run-ios instead of the sudo react-native run-ios.
Next try the following:
In file AppDelegate.m, change
jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];
To:
jsCodeLocation = [NSURL URLWithString:@"http://127.0.0.1:8081/index.ios.bundle?platform=ios&dev=true"];
(This may be a security issue with iOS 9);
Next try to reset your env.
