I am completely new to React Native. I followed the instructions from the Get Started page for React Native. These are the commands I've run so far:

-brew install node -brew install watchman -npm install -g react-native-cli

I created my project using this command: -react-native init AwesomeProject

I tried to run my app using: -react-native run-ios

Then I get an the build error. Even though the simulator opens up, the app does not open up. Please help.

** BUILD FAILED **


The following commands produced analyzer issues:

  • There's a bunch of issues on the React Native Github around the ":CFBundleIdentifier", Does Not Exist error. To narrow down the issue, could you post your: node, npm, and react-native versions as well as your package.json file. Also, check to see if anything is running on the default port used by React Native which I believe is 8081. Commented Jul 21, 2017 at 21:57
  • Thanks for your quick response. node v8.2.1 npm 5.3.0 react-native-cli: 2.0.1 react-native: 0.46.4 Commented Jul 21, 2017 at 22:42
  • I tried to see if anything is running on port 8081 using command "$ sudo lsof -i :8081" but I am getting "-bash: $: command not found". Also, how can I find my package.json file so I can post it here? Commented Jul 21, 2017 at 22:50
  • Remove the $ from your command and it should work. If this is not the issue, you can look here for some potential solutions. Commented Jul 21, 2017 at 23:01
  • @Igrizo Your package.json file should be in the root folder of the react native project. It was created when you ran react-native init AwesomeProject. Commented Jul 21, 2017 at 23:29

Reset to default

Ok, here's an update. I completely uninstalled everything (watchman, node, homebrew, npm, etc).

Then I started from scratch using the Quick Start guide from React Native. I installed node by downloading the zip from their website. Then followed by these commands:

npm install -g create-react-native-app

create-react-native-app AwesomeProject

cd AwesomeProject

npm start

npm run ios

During the first run, I got the same errors as before. Then I read that "reset content and settings" in the Simulator menu would help. I did this. My simulator restarted. Then i ran -"npm run ios" again, and it booted up without any errors. Now I'm up and running. Not sure exactly which part corrected my errors but these were the steps I took.
