Expo Something Went Wrong Error

Is this a bug report?

Have you read the Bugs section of the Contributing to React Native Guide?

Yes

Environment

2. node -v: v8.1.4
3. npm -v: 5.3.0
4. yarn --version (if you use Yarn): 0.27.5

Steps to Reproduce

(Write your steps here:)

1. Create new app using create-react-native-app
2. Run yarn start

Expected Behavior

Be able to view the app on my phone by scanning the QR code in Expo.

Actual Behavior

Outputs warning:

Warning: You are using npm version 5.3.0. There may be bugs in this version, use it at your own risk. We recommend version 4.6.1.

but seems to work fine otherwise. When opening the link in Expo I just get the error that something went wrong. In the log it states:

Uncaught Error: Packager is not running at http://XXX.XXX.X.X:19001

Reproducible Demo

Create an app using create-react-native-app.

Downgraded to 4.6.1 and the warning disappeared but the other behavior did not change. I will try asking on the expo channels.

Hello, have you resolved this issue? I just tried downgrading to 4.6.1 using the command: npm install npm@4.6.1 from within the RN project directory (then npm i after confirming the package.json file specified npm 4.6.1). I still get the same warning from Expo IDE and when I query npm -version from within the RN project directory, I get 5.3.0.

What am I doing wrong? Please advise - thank you 😄
