create-react-native-app: 'create-react-native-app' failing on my iOS device

Description

I followed the “get started” instructions, but I’m unable to open the app on iOS.

Observed Behavior

I ran “npm start,” navigated to exp://192.168.0.8:19000 (QR method times out) on my iOS device in the Expo app. There was no terminal output. However, there was this error in the Expo app:

"This experience uses an unsupported version of Expo (SDK 15.0.0). You may need to update Expo." (code undefined).

Environment

npm ls react-native-scripts: react-native-scripts@0.0.25
npm ls react-native: react-native@0.42.3
npm ls expo: expo@15.1.2
node -v: v6.0.0
npm -v: 3.8.6
yarn --version: n/a
watchman version: n/a

Operating system: Windows 10
Phone/emulator/simulator & version: iPhone 6 Plus 10.2 (14C92)

+1; I have the same issue as @juanmnl

Edit: I’ve found a solution that works for me when I try running the iOS simulator. After running npm run ios, I went to the simulator’s home page (Shift-CMD-H) and deleted the Expo app. Running npm run ios afterwards reinstalls the Expo app on the simulator.

I have the same issue, but on the iOS simulator. I started a brand new project and there’s no error in the console.

Node v7.7.4  
Npm 4.1.2  
expo@15.1.2  
react-native@0.42.3  
react-native-scripts@0.0.25  
watchman 4.7.0  
iPhone 6 simulator - IOS 10.2 (14c89)

on macOS Sierra 10.12.3.

@vidhyeshp - try downloading exp and running the project through that – npm i -g exp and then exp start
