Expo XDE cannot run applications. Tunnel packer not found

Question

Has anyone encountered this error:

Tunnel packager.yu-tyd.my-app.exp.direct not found

My application is just a welcome world

 import Expo from 'expo' import React from 'react' import { Text } from 'react-native' const App = () => ( <Text>Hello World</Text> ) Expo.registerRootComponent(App) 

Not sure what causes the error. Here are my dependencies:

  "dependencies": { "@expo/ex-navigation": "^2.9.2", "expo": "^15.0.2", "react": "~15.4.0", "react-native": "https://github.com/exponent/react-native/archive/sdk-15.0.0.tar.gz", "react-redux": "^5.0.3", "redux": "^3.6.0" } 

What can I lose?

Answer 1

I encountered the same error; In my case, my internet connection was unreliable and it couldn’t reach the local URL of the running code, since it cannot Tunnel there (Tunneling in Expo guarantees that we can run the code behind a VPN.

Expo Team Recommendation:

Note. If you are on MacOS and XDE is stuck in "Waiting for the Packer and Tunnel to Run," you may need to install a guard on your computer. The easiest way to do this is with Homebrew, brew, to set up a watchman.
